25631074 Cellular biotinylated semenogelin II protein (SEMG2) is incorporated into HIV-1 Gag virus-like particles
22177559 Peptides released by physiological cleavage of Semg1 and Semg2 form amyloids that enhance HIV infection.
21557275 These results suggest the involvement of semenogelins in prostate cancer and their prognostic values in predicting cancer progression after radical prostatectomy.
19089943 Semenogelins (Sgs) modifies the membrane structure, indirectly inhibiting motility, and provides suggestions for a therapy for male infertility through selection of a functional sperm population using Sgs.
18714013 antibacterial activity of the semenogelin-derived peptides generated in seminal plasma was strictly zinc-dependent both at neutral and low pH
18482984 semenogelins I and II were directly cleaved by KLK14. Semenogelins were also able to reverse KLK14 inhibition by Zn2+, providing a novel regulatory mechanism for KLK14 activity.
17683036 SGII is a novel target for protein S-nitrosylation in spermatozoa.
15563730 The binding of Zn2+ to SgI and SgII and their involvment in regulating the activity of PSA are reported.
14629036 structural changes in the semenogelin 1 and 2 proteins that have arisen since the human-chimpanzee-gorilla split may be responsible for the physiological differences between these species ejaculated semen that correlate with their sociosexual behavior
14581514 Seminal plasma motility inhibitor, one of the fragments of Sg, has its inhibitory effect on ejaculated spermatozoa in liquefied semen under physiological conditions.
12200457 SgII transcripts were demonstrated in several tissues, with the strongest signals coming from seminal vesicles, vas deferens, prostate, epididymis and trachea.
