Mechanistic narrative

Synthesis pass · prose summary of the discoveries below

PPP1R16B/TIMAP is a prenylated, CAAX-box-dependent plasma-membrane-anchored regulatory subunit of protein phosphatase 1 that controls endothelial barrier integrity, migration, and angiogenesis by targeting and tuning PP1c activity toward specific membrane substrates (PMID:12055102, PMID:18586956, PMID:25007873). Through its ankyrin-repeat cluster and PP1-interacting domain it preferentially binds the β-isoform of PP1c (PP1cβ) and acts as a substrate-targeting scaffold, recruiting the phosphatase to LAMR1, moesin/ERM proteins, MLC2, merlin (phospho-Ser518), eEF1A1, and ECE-1 to govern their dephosphorylation and membrane localization (PMID:16263087, PMID:18586956, PMID:23685145, PMID:26497934, PMID:26806547, PMID:27871951). The complex exerts dual, substrate-dependent effects on PP1c: TIMAP-bound PP1cβ efficiently dephosphorylates MLC2 and ERM substrates, yet TIMAP also inhibits PP1c toward other substrates and, by competing with MYPT1 for PP1cβ and occluding the active site, antagonizes myosin phosphatase to paradoxically promote MLC2 phosphorylation (PMID:23685145, PMID:31315927). TIMAP activity is set by a layered phospho-code: PKA-primed GSK-3β phosphorylation at Ser333/Ser337 relieves PP1c inhibition and drives filopodia and barrier protection, PKCα phosphorylation at Ser331 blocks ERM dephosphorylation and slows barrier recovery, and PLK4 phosphorylation at Ser69 promotes membrane enrichment and migration (PMID:17609201, PMID:21466834, PMID:27939168, PMID:34343028). TIMAP positively regulates PTEN/Akt signaling required for endothelial proliferation, survival, and angiogenic sprouting (PMID:25007873), and its expression is repressed by TGF-β via HDAC3-associated Smad2/3 and by BMP9 via SMAD1/5/8 while induced by hypoxia and angiogenic growth factors, with TIMAP loss reducing tumor angiogenesis in vivo (PMID:27709267, PMID:39344413).

2002 TIMAP (PPP1R16B) contains five ankyrin repeats, a PP1-interacting domain, and a COOH-terminal CAAX box; a GFP-TIMAP fusion protein localizes to the plasma membrane in a CAAX box-dependent fashion, and TGF-β1 represses TIMAP through a protein synthesis- and histone deacetylase-dependent process.

2005 TIMAP interacts with the 37/67 kDa laminin receptor (LAMR1) via its fourth ankyrin repeat (amino acids 261–290); this interaction recruits PP1 to LAMR1 and targets PP1-mediated dephosphorylation of LAMR1, as full-length TIMAP (but not the ankyrin-deletion mutant) abolished LAMR1 phosphorylation in cells. Yeast two-hybrid, co-immunoprecipitation, co-localization at plasma membrane, domain-deletion mutagenesis, in vitro PP1 phosphatase assay Biochemical and biophysical research communications High 16263087
2007 TIMAP is phosphorylated by PKA at Ser333/Ser337 and, after PKA priming, by GSK-3β at the same sites; this phosphorylation controls TIMAP association with PP1c and PP1c activity. Abolishing PP1c binding (TIMAPV64A/F66A) causes hyper-phosphorylation of TIMAP, indicating that TIMAP-associated PP1c auto-dephosphorylates TIMAP. Reduced PP1c activity (via TIMAP mutants with low PP1c binding) strongly stimulates endothelial cell filopodia formation.

2008 Recombinant TIMAP preferentially binds the β-isoform of PP1c (PP1cβ) from pulmonary artery endothelial cells. TIMAP depletion by siRNA attenuates barrier-protective responses and enhances barrier disruption. TIMAP co-immunoprecipitates with moesin and is involved in PKA-mediated moesin dephosphorylation at the cell periphery, contributing to endothelial barrier protection. Pull-down assay with isoform-specific PP1c, siRNA depletion with transendothelial electrical resistance measurements, immunofluorescent co-localization, co-immunoprecipitation, forskolin/PKA activation experiments American journal of physiology. Lung cellular and molecular physiology High 18586956
2011 Non-phosphorylated TIMAP binds PP1c with a binding constant Ka = 1.80 × 10⁶ M⁻¹ (surface plasmon resonance). PKA mono-phosphorylation slightly decreases the dissociation rate; double (PKA+GSK3β) phosphorylation of TIMAP does not substantially reduce PP1c binding but strongly attenuates TIMAP's inhibitory effect on PP1c activity toward phospho-moesin substrate (<10% inhibition vs ~60% for non-phosphorylated TIMAP). PKA activation followed by GSK3β activation is required for the barrier-protective effect of forskolin in thrombin-treated endothelial cells. Surface plasmon resonance binding assay, in vitro thiophosphorylation, phosphatase activity assay with phospho-moesin substrate, specific GSK3β inhibitor in bovine pulmonary endothelial cells Biochimie High 21466834
2013 TIMAP associates with all three PP1c isoforms in vitro but endogenous TIMAP in endothelial cells preferentially co-immunoprecipitates PP1cβ. Structural modeling predicts PP1c C-terminus is buried in the TIMAP ankyrin cluster while the active site remains accessible—consistent with experiments showing PP1c C-terminal phosphorylation by cdk2-cyclinA is masked by TIMAP. TIMAP inhibits PP1c activity toward phosphorylase a (IC₅₀ ~0.4–1.2 nM). TIMAP-bound PP1cβ effectively dephosphorylates MLC2 (direct substrate), while TIMAP inhibits PP1cβ activity toward LAMR1 by masking its phosphorylation sites. TIMAP C-terminal length and Ser333/Ser337 phosphomimic mutations modulate the inhibitory effect. Co-immunoprecipitation, in vitro phosphatase activity assays (phosphorylase a, MLC2, LAMR1), structural modeling, site-directed mutagenesis, C-terminal truncation variants Biochemical and biophysical research communications High 23685145
2014 TIMAP is necessary for Akt-dependent endothelial cell proliferation, survival, and angiogenic sprout formation. TIMAP and PTEN co-localize and co-immunoprecipitate in endothelial cells. TIMAP depletion reduces inhibitory phosphorylation of PTEN at S370 (but not S380/T382/T383), leading to reduced Akt phosphorylation; this effect is rescued by the PTEN inhibitor bpV(phen), placing TIMAP upstream of PTEN/Akt. siRNA depletion, impedance-based proliferation assay, EdU incorporation, caspase 3 activity, 3D angiogenic sprouting assay, co-immunoprecipitation, co-localization, pharmacological PTEN inhibition rescue American journal of physiology. Renal physiology High 25007873
2015 TIMAP directly interacts with eukaryotic elongation factor 1A1 (eEF1A1) via a TD-NEM-like motif in TIMAP. TIMAP regulates membrane localization of eEF1A1 (eEF1A1 disappears from the membrane in TIMAP-depleted cells). ROCK-phosphorylated eEF1A1 is a substrate for the TIMAP-PP1 complex.

2016 TGF-β transcriptionally downregulates TIMAP through HDAC3-associated Smad2/3 signaling; HDAC3 is recruited to the Smad binding element on the TIMAP promoter. TIMAP dephosphorylates myosin light chain (MLC) in macrophages, and TGF-β-induced macrophage migration and phagocytosis occur in a TIMAP- and MLC-phosphorylation-dependent manner.

2016 PKCα phosphorylates TIMAP at Ser331 in vitro and in endothelial cells. PKC-phosphorylated TIMAP is enriched at the plasma membrane, but phospho-Ser331 TIMAP shows severely reduced binding to ERM proteins, inhibiting TIMAP-PP1 activity toward phospho-ERM. Phosphomimic S331D TIMAP increases membrane phospho-ERM levels while phosphonull S331A lowers them, indicating Ser331 phosphorylation by PKC inhibits ERM dephosphorylation and slows endothelial barrier recovery.

2016 TIMAP-PP1c complex interacts with endothelin converting enzyme-1 (ECE-1); TIMAP depletion reduces TIMAP-PP1c activity toward ECE-1, causing increased ECE-1 at the plasma membrane and elevated endothelin-1 secretion.

2016 PP1c-TIMAP complex dephosphorylates merlin at Ser518 in endothelial cells. TIMAP N-terminal half (aa 1–290) interacts with the FERM domain of merlin, and PP1c is present in TIMAP-merlin complexes. Without TIMAP, PP1c cannot bind merlin. TIMAP or PP1c depletion increases phospho-Ser518 merlin at the membrane. EBP50 binds unphosphorylated merlin in the nucleus and is required for merlin's nuclear localization.

2019 TIMAP inhibits myosin phosphatase activity in endothelial cells by competing with MYPT1 for PP1cβ and blocking the PP1cβ active site. Excess TIMAP reduces MYPT1-PP1cβ association and leads to proteasomal MYPT1 degradation. TIMAP-associated PP1cβ does not interact with microcystin-LR (active-site inhibitor), indicating the active site is blocked when PP1cβ is bound to TIMAP. TIMAP overexpression paradoxically enhances MLC2 phosphorylation by displacing the more active myosin phosphatase MYPT1/PP1cβ.

2021 TIMAP-PP1c forms a complex with laminin receptor (LR) on the cell membrane (LR-TIMAP/PP1c complex). pTyr47-LR determines the stability of this complex. TIMAP/PP1c binding to LR activates PP1c phosphatase activity and regulates LR phosphorylation at Thr125; low phospho-LR stabilizes the complex and maintains endothelial barrier integrity via regulation of VE-cadherin Ser665 phosphorylation.

2021 Phosphorylation of TIMAP at Ser69 by polo-like kinase 4 (PLK4) promotes enrichment of TIMAP at the plasma membrane and increases membrane protrusions, leading to faster wound healing and endothelial cell migration. Ser69 phosphorylation does not affect binding of PP1c, ERM, or RACK1 to TIMAP. Phosphomimic S69D TIMAP showed enhanced membrane localization compared to wild-type.

2023 TIMAP is expressed in SH-SY5Y neuroblastoma cells, is downregulated during neuronal differentiation, and its overexpression inhibits differentiation.
