Les proteines majeures de la secretion prostatique

Human prostatic secretion contains only a few major proteins among which one finds albumin, acid phosphatase, prostate specific antigen (PSA), prostatic secretory protein of 94 amino acids (PSP94), Zn-α₂-glycoprotein and α₁-acid glycoprotein. The roles of most of these proteins are not entirely known. However, PSA has been shown to contribute to the hydrolysis of the seminal coagulum proteins. Probable roles for the other components include modifications of the properties of spermatozoa surface and control of inflammatory responses in male and female urogenital tracts.
