Mechanistic narrative

Synthesis pass · prose summary of the discoveries below

PRSS21 (testisin/ESP-1) is a GPI-anchored, trypsin-like serine protease that operates in two distinct biological settings: male germ cell maturation and fertilization, and endothelial/vascular regulation (PMID:11861648, PMID:18754795, PMID:30911775). The mature protein carries a canonical His-Asp-Ser catalytic triad and a C-terminal hydrophobic GPI-anchor extension that targets it to Triton X-100-insoluble lipid raft microdomains of the cell surface (PMID:11861648, PMID:9826525). In spermatozoa, testisin is required for epididymal sperm maturation, maintaining tail integrity and osmotic regulatory capacity during epididymal transit, and for fertilization steps including zona pellucida binding, ZP-induced acrosome reaction, and cumulus/ZP penetration; this proteolytic function acts redundantly with acrosin and can be compensated by uterine factors in vivo (PMID:18754795, PMID:19571264, PMID:20484738). On the sperm surface it assembles into high-molecular-weight multiprotein complexes with zona pellucida-binding proteins including ZPBP, ZAN, and acrosin, and its processing to the mature form depends on SPEM2 (PMID:30549223, PMID:38421455). In ovarian cancer and microvascular endothelial cells, catalytically active testisin activates the receptor PAR-2 to suppress secretion of pro-angiogenic ANG2 and ANGPTL4 and maintains VE-cadherin-mediated adherens junctions, thereby restraining vascular leak, tumor seeding, and metastasis (PMID:30911775, PMID:32511276). In testicular germ cell tumors, PRSS21 expression is silenced by 5'-CpG island hypermethylation and histone deacetylation, and its re-expression suppresses anchorage-dependent growth and xenograft tumor formation, defining a tumor suppressor activity (PMID:15685234).

2002 PRSS21 (TESP5/testisin/esp-1) is a GPI-anchored serine protease on the sperm cell surface. When HEK293 cells were transformed with an expression plasmid carrying the entire PRSS21 protein-coding region, the recombinant protein was released from the cell membrane by treatment with Bacillus cereus phosphatidylinositol-specific phospholipase C, confirming GPI-anchoring. The 42- and 41-kDa forms were selectively included into Triton X-100-insoluble lipid raft microdomains of sperm membranes. Enzymatic properties of recombinant TESP5 were similar to but distinct from rat acrosin and pancreatic trypsin in substrate specificity and sensitivity to serine protease inhibitors.

1998 PRSS21 (ESP-1) encodes a membrane-type serine protease with a signal peptide of 18 amino acids, a propeptide of 23 amino acids, a catalytic domain containing the canonical serine protease catalytic triad (His, Asp, Ser), and a C-terminal hydrophobic stretch indicating membrane anchoring. The gene is most abundantly expressed in testis and prostate, with expression also in eosinophils (but not neutrophils), mononuclear cells, lung, spleen, and pancreas. cDNA cloning from human eosinophils, deduced amino acid sequence analysis, tissue distribution by Northern/RT-PCR Biochemical and biophysical research communications Medium 9826525
1999 The ESP-1/PRSS21 gene spans approximately 4.6 kb, consists of 6 exons and 5 introns, and maps to chromosome 16p13.3. A new splicing variant was identified from HeLa cell cDNA. Dual-luciferase reporter analysis revealed that a GC-rich region between nucleotide positions -106 and -189 (containing one AP-1/Sp-1 binding site) is responsible for minimum promoter activity in HeLa cells. The transcription initiation site is at position -106 (residue G).

2000 The human PRSS21 gene is approximately 4.5 kb, contains 6 exons and 5 introns, and localizes to chromosome 16p13.3 between microsatellite marker D16S246 and radiation hybrid breakpoint CY23HA. Two known isoforms of testisin are generated by alternative pre-mRNA splicing. The 5'-flanking region lacks a TATA box but contains a CCAAT sequence, a CpG island, and consensus elements for Sp1, AP1, and testis-specific transcription factors. Testisin is expressed in premeiotic testicular germ cells but not in testicular tumor cell lines, and is aberrantly expressed in some non-testis tumor cell lines.

2001 The murine Prss21 gene has six exons and five introns spanning approximately 5 kb, localizes to murine chromosome 17A3.3-B (syntenic with human 16p13.3), and encodes a 324-amino acid protein with an N-terminal signal sequence, a pro-region, a 251-amino acid catalytic domain with trypsin-like specificity, and a C-terminal hydrophobic GPI-anchor extension. Immunostaining localized murine Testisin to the cytoplasm and plasma membrane of round and elongating spermatids. mRNA expression onset at approximately day 18 post-birth corresponds to the appearance of spermatids, indicating temporal regulation during spermatogenesis.

2005 Hypermethylation of a 385 bp 5'-CpG island in the PRSS21 (testisin) promoter silences its expression in 100% of testicular germ cell tumors (8/8) and multiple tumor cell lines, as shown by bisulfite sequencing. Treatment of testisin-negative cell lines with demethylating agents and/or histone deacetylase inhibitor reactivated testisin expression. Stable expression of testisin in the testisin-negative Tera-2 testicular cancer line suppressed anchorage-dependent growth and tumor formation in SCID mice, establishing a tumor suppressor function.

2005 PRSS21 and related serine proteases (tryptase 5/Prss32, pancreasin/Prss27, testis serine protease-1) are inserted into plasma membranes via glycosylphosphatidylinositol (GPI) anchors, as demonstrated by phosphatidylinositol-specific phospholipase C release, and are consequently targeted to lipid rafts.

2008 Prss21-null epididymal sperm penetrate the zona pellucida (ZP) at very low rates in vitro, due to reduced ability to bind the ZP and undergo ZP-induced acrosome reaction. Sperm-egg fusion in vitro was also severely impaired. Importantly, the reduced fertility of Prss21-null epididymal sperm was rescued by exposure to the uterine microenvironment (in vivo passage through uterus or in vitro treatment with uterine fluids), demonstrating that PRSS21's proteolytic function in ZP penetration can be compensated by uterine factors.

2009 PRSS21-deficient spermatozoa show decreased motility, angulated and curled tails, fragile necks, and dramatically increased susceptibility to decapitation during epididymal transit. Histological and electron microscopic analyses showed increased curling and detachment of tails as spermatozoa transit from corpus to cauda epididymis. Cauda epididymal spermatozoa deficient in PRSS21 fail to mount a swelling response to hypotonic conditions, indicating impaired osmotic regulatory ability. These defects identify PRSS21 as a novel proteolytic factor directing epididymal sperm maturation and fertilizing ability.

2010 Double-knockout mice lacking both ACR (acrosin) and PRSS21 are subfertile in vivo, and their sperm are unable to undergo acrosomal exocytosis on the zona pellucida surface or traverse the ZP in vitro, and are also defective in penetrating the cumulus matrix. Artificial insemination directly into the uterus partially rescued fertilization, as did the presence of uterine fluids in vitro. This demonstrates that the trypsin-like protease activity of ACR and PRSS21 together is essential for sperm penetration through cumulus matrix and ZP in vitro, while female reproductive tract factors can partially compensate in vivo.

2018 Testisin (PRSS21) surface expression on stallion spermatozoa increases significantly upon capacitation and further increases after acrosome reaction, with localization to the equatorial region of the sperm head. Testisin is also found in epididymal luminal fluid and epithelial cells. Blue Native PAGE and co-immunoprecipitation followed by mass spectrometry revealed that testisin forms several high-molecular-weight multiprotein complexes and interacts with zona pellucida-binding proteins including ZPBP, ZAN, acrosin, multiple heat-shock proteins, and components of the TCP1 complex, indicating participation in the ZP-binding complex.

2019 In a murine xenograft model of ovarian intraperitoneal tumor metastasis, increased tumor testisin expression inhibited intraperitoneal tumor seeding, colonization, ascites accumulation, and metastatic tumor burden in a manner dependent on catalytically active testisin. Testisin activity suppresses the synthesis and secretion of pro-angiogenic angiopoietins ANG2 and ANGPTL4 (which promote vascular leak and edema). Gene profiling and mechanistic studies support a model wherein testisin activates protease-activated receptor-2 (PAR-2) as a substrate to antagonize pro-angiogenic angiopoietins that modulate vascular permeability.

2020 Testisin (PRSS21)-deficient mice (Prss21-/-) show a substantially increased incidence and severity of hemorrhages during corpus luteal development, associated with increased vascular leakiness (greater Evans blue dye extravasation). siRNA knockdown of testisin in microvascular endothelial cells impaired reorganization and tubule-like formation on Matrigel and increased paracellular permeability to FITC-albumin, associated with decreased VE-cadherin expression and increased phospho(Tyr658)-VE-cadherin levels. Tight junction proteins occludin, claudin-5, and ZO-1 were unaffected. These data identify testisin as a novel regulator of VE-cadherin-mediated endothelial adherens junctions during angiogenesis.
