Plasma serine protease inhibitor (SERPINA5) is a glycoproteins that inhibit serine proteases. SERPINA5 is involved in the regulation of intravascular and extravascular proteolytic activities, controls the sperm motility and fertilization and protect components of the genital tract. SERPINA5 also inhibits urinary-type plasminogen activator-dependent tumor cell invasion and metastasis. Serpin A5 Protein, Human (HEK293, His) is the recombinant human-derived Serpin A5 protein, expressed by HEK293 , with C-6*His labeled tag. The total length of Serpin A5 Protein, Human (HEK293, His) is 387 a.a., with molecular weight of 44-55 kDa.

Plasma serine protease inhibitor (SERPINA5) is a member of the serpin family of proteins, a group of glycoproteins that inhibit serine proteases. SERPINA5 is a heparin-dependent serine protease inhibitor acting in body fluids and secretions which inactivates serine proteases by binding irreversibly to their serine activation site. SERPINA5 is involved in the regulation of intravascular and extravascular proteolytic activities in a bimodal fashion. SERPINA5 plays hemostatic roles in the blood plasma, acts as a procoagulant and pro-inflammatory factor by inhibiting the anticoagulant activated protein C factor as well as the generation of activated protein C factor by the thrombin/thrombomodulin complex. Otherwise, SERPINA5 can 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, SERPINA5 inactivates several serine proteases implicated in the reproductive system as SERPINA5 inhibits the serpin acrosin to indirectly protect 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, SERPINA5 inhibits urinary-type plasminogen activator and kallikrein activities. SERPINA5 inactivates membrane-anchored serine proteases activities such as MPRSS7 and TMPRSS11E; inhibits urinary-type plasminogen activator-dependent tumor cell invasion and metastasis, SERPINA5 may also play a non-inhibitory role in seminal plasma and urine as a hydrophobic hormone carrier by its binding to retinoic acid [1] [2] [3] .
