Synthesis pass · prose summary of the discoveries below

DIAPH1 (mDia1) is an autoinhibited Rho-family GTPase effector that nucleates and processively elongates unbranched actin filaments, coordinating the actin and microtubule cytoskeletons to drive cell migration, polarity, division, and immune and vascular signaling (PMID:10559899, PMID:11146620, PMID:14657240). In the resting state, an intramolecular DID-DAD interaction holds the protein inactive; GTP-RhoA binds the regulatory N-terminal domain at a site that overlaps the DAD-binding surface, displacing the DAD and releasing the FH1-FH2 module, as defined by crystal and NMR structures of the dimeric N-terminal armadillo-repeat domain and of an N-terminal/FH2-DAD assembly (PMID:15866170, PMID:20927338). The released FH2 domain dimerizes to nucleate actin, protects barbed ends from capping protein, and elongates filaments processively while undergoing helical rotation around the filament; the FH1 domain recruits profilin-actin and this rotation renders filaments resistant to cofilin severing (PMID:12906795, PMID:14657240, PMID:21148346, PMID:29760064). mDia1 nucleation frequency is tuned directly by free G-actin concentration, and its activity is further modulated by cofactors including Flightless-I, APC, and SPIN90-Arp2/3, the latter coupling linear mDia1 elongation to branched network formation (PMID:18827014, PMID:20223827, PMID:20566685, PMID:32572169). Through these activities mDia1 builds stress fibers downstream of RhoA in balance with ROCK, drives force-induced focal adhesion maturation and mechanosensitive stress-fiber repair, activates serum response factor by depleting the G-actin pool, and aligns microtubules with actin to control cell polarity, MTOC orientation, and focal-adhesion turnover (PMID:10559899, PMID:11402062, PMID:12429848, PMID:16943426, PMID:34822787). It directly binds and engages microtubules through the FH2 domain and acts in formin cascades with INF2 (scaffolded by IQGAP1) and with capping protein to generate stable detyrosinated microtubules (PMID:21998204, PMID:22918941, PMID:27030671). mDia1 also serves as the essential membrane-proximal cytoplasmic effector of RAGE, binding the RAGE cytoplasmic tail to transduce ligand-stimulated AKT signaling, a protein-protein interaction that is pharmacologically tractable and whose inhibition attenuates diabetic complications and vascular neointimal expansion (PMID:22194616, PMID:22511750, PMID:26936329, PMID:34818060). In vivo it is required for T lymphocyte trafficking, NK and macrophage cytoskeletal organization, TCR-driven spatiotemporal LAT phosphorylation, hematopoietic progenitor homeostasis, megakaryocyte proplatelet formation, and male fertility, and is phosphorylated by Cdk1 to restrain profilin binding and cortical tension during metaphase, preventing inappropriate spindle assembly checkpoint activation (PMID:17682067, PMID:17699759, PMID:19427913, PMID:19234535, PMID:25298036, PMID:30816115, PMID:30256801, PMID:31911947). Gain-of-function truncations that delete the DAD constitutively activate DIAPH1, causing increased F-actin and stabilized microtubules, macrothrombocytopenia, and DFNA1 sensorineural hearing loss (PMID:26912466, PMID:27707755).

2005 Crystal structure of the dimeric mDia1 regulatory N-terminal domain reveals an intertwined six-helix bundle with two armadillo-repeat DIDs; NMR and biochemical mapping show that RhoA and DAD binding sites partially overlap on the DID, explaining how RhoA activates mDia1 by competing with DAD; RhoA binding also requires a flexibly tethered arm adjacent to the DID.
