Target type: molecularfunction
Catalysis of the reaction: 1D-myo-inositol 1,4,5-trisphosphate + ATP = 1D-myo-inositol 1,3,4,5-tetrakisphosphate + ADP + H+. [RHEA:11020]
Inositol-1,4,5-trisphosphate 3-kinase (IP3 3-kinase) activity catalyzes the phosphorylation of inositol 1,4,5-trisphosphate (IP3) at the 3-hydroxyl position, generating inositol 1,3,4,5-tetrakisphosphate (IP4). This reaction is a key step in the phosphoinositide signaling pathway, which plays a crucial role in various cellular processes including calcium mobilization, cell growth, and apoptosis. IP3 3-kinase is a member of the AGC kinase family and its activity is regulated by a variety of factors, including calcium, diacylglycerol, and protein-protein interactions. The enzyme is essential for the proper functioning of the phosphoinositide signaling pathway, and its dysregulation has been implicated in several human diseases, including cancer and diabetes.'
