This gene is one in a cluster of serpin genes located on the q arm of chromosome 14. This family member is a glycoprotein that can inhibit several serine proteases, including protein C and various plasminogen activators and kallikreins, and it thus plays diverse roles in hemostasis and thrombosis in multiple organs. [provided by RefSeq, Aug 2012]. * **UniProt Summary**: Heparin-dependent serine protease inhibitor acting in body fluids and secretions. Inactivates serine proteases by binding irreversibly to their serine activation site. Involved in the regulation of intravascular and extravascular proteolytic activities. Plays hemostatic roles in the blood plasma. Acts as a procoagulant and proinflammatory factor by inhibiting the anticoagulant activated protein C factor as well as the generation of activated protein C factor by the thrombin/thrombomodulin complex. Acts as an anticoagulant factor by inhibiting blood coagulation factors like prothrombin, factor XI, factor Xa, plasma kallikrein and fibrinolytic enzymes such as tissue- and urinary- type plasminogen activators. In seminal plasma, inactivates several serine proteases implicated in the reproductive system. Inhibits the serpin acrosin; indirectly protects component of the male genital tract from being degraded by excessive released acrosin. Inhibits tissue-and urinary-type plasminogen activator, prostate-specific antigen and kallikrein activities; has a control on the sperm motility and fertilization. Inhibits the activated protein C-catalyzed degradation of SEMG1 and SEMG2; regulates the degradation of semenogelin during the process of transfer of spermatozoa from the male reproductive tract into the female tract. In urine, inhibits urinary-type plasminogen activator and kallikrein activities. Inactivates membrane-anchored serine proteases activities such as MPRSS7 and TMPRSS11E. Inhibits urinary-type plasminogen activator-dependent tumor cell invasion and metastasis. May also play a non-inhibitory role in seminal plasma and urine as a hydrophobic hormone carrier by its binding to retinoic acid. {ECO:0000269|PubMed:10340997, ECO:0000269|PubMed:11722589, ECO:0000269|PubMed:14696115, ECO:0000269|PubMed:15140131, ECO:0000269|PubMed:15328353, ECO:0000269|PubMed:15853774, ECO:0000269|PubMed:1725227, ECO:0000269|PubMed:18467335, ECO:0000269|PubMed:2844223, ECO:0000269|PubMed:3501295, ECO:0000269|PubMed:6323392, ECO:0000269|PubMed:7521127, ECO:0000269|PubMed:7548057, ECO:0000269|PubMed:8536714, ECO:0000269|PubMed:8665956, ECO:0000269|PubMed:9473218, ECO:0000269|PubMed:9510955, ECO:0000269|PubMed:9556620}. |Serpin| |protein C inhibitor-coagulation factor V complex| |protein C inhibitor-coagulation factor XI complex| |protein C inhibitor-TMPRSS11E complex| |protein C inhibitor-PLAT complex| |protein C inhibitor-TMPRSS7 complex| |protein C inhibitor-KLK3 complex| |protein C inhibitor-plasma kallikrein complex| |protein C inhibitor-coagulation factor Xa complex| |protein C inhibitor-thrombin complex| |protein C inhibitor-PLAU complex| |seminal vesicle development| |platelet dense tubular network| |acrosin binding| |platelet alpha granule| |fusion of sperm to egg plasma membrane involved in single fertilization| |acrosomal membrane| |plasma membrane fusion| |glycosaminoglycan binding| |retinoic acid binding| |phosphatidylcholine binding| |serine-type endopeptidase inhibitor activity| |protease binding| |membrane fusion| |single fertilization| |fertilization| |heparin binding| |negative regulation of endopeptidase activity| |negative regulation of peptidase activity| |blood coagulation| |coagulation| |lipid transport| |hemostasis| |lipid localization| |negative regulation of proteolysis| |cellular process involved in reproduction in multicellular organism| |collagen-containing extracellular matrix| |external side of plasma membrane| |gland development| |regulation of endopeptidase activity| |reproductive structure development| |reproductive system development| |regulation of peptidase activity| |negative regulation of hydrolase activity| |wound healing| |regulation of body fluid levels| |spermatogenesis| |male gamete generation| |response to wounding| |protein-containing complex| |developmental process involved in reproduction| |gamete generation| |regulation of proteolysis| |negative regulation of catalytic activity| |multicellular organismal reproductive process| |sexual reproduction| |multicellular organism reproduction| |membrane organization| |multi-organism reproductive process| |negative regulation of cellular protein metabolic process| |negative regulation of protein metabolic process| |negative regulation of molecular function| |regulation of hydrolase activity| |reproductive process| |reproduction| |extracellular space| |extracellular region| |membrane| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp346|CoCl2 18μM R07 exp346]]|1.84| |[[:results:exp354|Diepoxybutane 3μM R07 exp354]]|2.12| No correlation found to any other genes in chemogenomics.
