General description

Inhibin β-Subunit (also called as MSMB, microseminoprotein-β) is a cysteine-rich and nonglycosylated protein. It is one of the major components of semen.

Biochem/physiol Actions

Inhibin β-Subunit (also called as MSMB, microseminoprotein-β) is upregulated in ovarian cancer and is correlated with the levels of prostasin. Low expression of MSMB is linked with increased risk of prostate cancer. It is involved in the inhibition of FSH (follicle stimulating hormone), thereby abolishing growth-enhancing activity of FSH in prostate cancer.

Marni Stott-Miller et al.
The Prostate, 73(16), 1803-1809 (2013-09-17)
Recently, a genetic variant (rs10993994) in the MSMB gene associated with prostate cancer (PCa) risk was shown to correlate with reduced prostate secretory protein of 94 amino acids (PSP94) levels. Although the biological activity of PSP94 is unclear, one of
Nicholas Shukeir et al.
Cancer research, 63(9), 2072-2078 (2003-05-03)
Prostate cancer is a common malignancy affecting men, which is often associated with skeletal metastases resulting in significant morbidity and mortality. In this hormone-dependent cancer, low levels of a prostate secretory protein of 94 amino acids (PSP-94) are associated with
N J Arbatti et al.
FEBS letters, 181(1), 57-63 (1985-02-11)
The complete synthesis of the C-terminal 28 residues segment 67-94 of human seminal plasma beta-Inhibin, called beta 2-Inhibin, is reported. The Inhibin-like activity of the native 94 amino acids beta-Inhibin is compared to that of the synthetic replica of beta
S D Mahale et al.
International journal of peptide and protein research, 42(2), 132-137 (1993-08-01)
Observation of contradictory results with the in vitro assays for inhibin-like activity of the carboxyl terminal 28 amino acid peptide 67-94 with a disulfide loop, of human seminal plasma inhibin (HSPI), prompted us to synthesize both the linear and the
J-x Ma et al.
Cell death & disease, 5, e1407-e1407 (2014-09-05)
Ovarian cancer is a leading cause of cancer death as diagnosis is frequently delayed to an advanced stage. Effective biomarkers and screening strategies for early detection are urgently needed. In the current study, we identify PSP94 as a key upstream
