Gene Gene information from NCBI Gene database.
Entrez ID 3633
Gene name Inositol polyphosphate-5-phosphatase B
Gene symbol INPP5B
Synonyms (NCBI Gene)
5PTase
Chromosome 1
Chromosome location 1p34.3
Summary This gene encodes a member of a family of inositol polyphosphate-5-phosphatases. These enzymes function in the regulation of calcium signaling by inactivating inositol phosphates. The encoded protein is localized to the cytosol and mitochondria, and assoc

Protein name Type II inositol 1,4,5-trisphosphate 5-phosphatase (EC 3.1.3.36) (75 kDa inositol polyphosphate-5-phosphatase) (Phosphoinositide 5-phosphatase) (5PTase)
Protein function Hydrolyzes phosphatidylinositol 4,5-bisphosphate (PtIns(4,5)P2) and the signaling molecule phosphatidylinositol 1,4,5-trisphosphate (PtIns(1,4,5)P3), and thereby modulates cellular signaling events.
