prps 2

PRPS2, a subset of PRS, is reported to be a potential protein associated with Sertoli-cell only syndrome. PRPS2 expression correlates with Sertoli-cell only syndrome and inhibits the apoptosis of TM4 Sertoli cells via the p53 Bcl-2 caspases signaling pathway. The gene for PRS II (PRPS2) is located at a different region of the X chromosome, namely Xpter-a21. The promoter region of the human PRPS2 gene was also GC-rich and contained a TATA-like sequence, four Sp1 binding sites and a homopyrimidine stretch.
