Summaries for INPP5B Gene

Entrez Gene Summary for INPP5B Gene

  • 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 associates with membranes through an isoprenyl modification near the C-terminus. Alternatively spliced transcript variants of this gene have been described. [provided by RefSeq, Jul 2014]

GeneCards Summary for INPP5B Gene

INPP5B (Inositol Polyphosphate-5-Phosphatase, 75kDa) is a Protein Coding gene. Diseases associated with INPP5B include oculocerebrorenal syndrome. Among its related pathways are Signaling by GPCR and Rho GTPase cycle. GO annotations related to this gene include phosphatidylinositol-4,5-bisphosphate 5-phosphatase activity and inositol-1,4,5-trisphosphate 5-phosphatase activity. An important paralog of this gene is SYNJ2.

UniProtKB/Swiss-Prot for INPP5B Gene

  • 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.

P32019

UniProtKB/Swiss-Prot:

I5P2_HUMAN :
  • P32019
Domain:
  • The ASH (ASPM-SPD2-Hydin) and RhoGAP (Rho GTPase activating) domains form a single folding module. The ASH domain has an immunoglobulin-like fold, the Rho-GAP domain lacks the catalytic arginine and is catalytically inactive. The ASH-RhoGAP module regulates the majority of the protein-protein interactions currently described. The ASH domain mediates association with membrane-targeting Rab GTPases. The Rho-GAP domain interacts with the endocytic adapter APPL1, which is then displaced by FAM109A and FAM109B as endosomes mature, all three interactions relie on F&H motifs, an approximately 12-13 amino-acid sequence centered around Phe and His residues essential for binding (By similarity).
  • Contains 1 PH domain.
  • Contains 1 Rho-GAP domain.
Family:
  • Belongs to the inositol 1,4,5-trisphosphate 5-phosphatase type II family.
