P6-hexaphosphate hydrolase 3-alpha
功能Cleaves a beta-phosphate from the diphosphate groups in PP-InsP5 (diphosphoinositol pentakisphosphate), suggesting that it may play a role in signal transduction. Also able to catalyze the hydrolysis of dinucleoside oligophosphates, with Ap6A and Ap5A being the preferred substrates. The major reaction products are ADP and p4a from Ap6A and ADP and ATP from Ap5A. Also able to hydrolyze 5-phosphoribose 1-diphosphate.
组织特异性Mainly expressed in testis and, at lower level in brain. According to PubMed:12121577, it is widely expressed.
序列相似性Belongs to the Nudix hydrolase family. DIPP subfamily. Contains 1 nudix hydrolase domain.
