Common Name1D-Myo-Inositol 1,3,4,5-tetrakisphosphate
Descriptionmyo-Inositol 1,3,4,5-tetrakisphosphate (CAS: 102850-29-3), also known as IP4, is a second messenger responsible for mediating Ca2+ entry through the plasma membrane and mobilizing intracellular Ca2+ by acting synergistically with inositol 1,4,5-trisphosphate (IP3). Inositol 1,4,5-trisphosphate 3-kinase (IP3K, EC 2.7.1.127) phosphorylates IP3 into IP4. Evidence shows that IP4 can activate a protein with ras- and rap-GAP activity and finally inactivate the G protein. This indicates that IP4 regulates Ca2+ influx in a GTP-dependent way, which potentially links the IP3 signalling pathway to GTP-regulated signalling mechanisms. IP4 is demonstrated to be a common regulator in Ca2+ homeostasis. IP4 can bind with a high affinity to several intracellular proteins: synaptotagmin (I and II), Gap1, Btk, and centaurin-alpha and may interact with synaptotagmin to inhibit synaptic transmission. IP4 also acts as a mediator in neuronal death in the ischemic hippocampus. IP4 production is not always associated with a modification in calcium concentration, and control of calcium mobilization is not the sole function proposed for IP4. IP4 defines an essential signalling pathway for T cell precursor responsiveness and development. In the thymus, IP4 is essential during the positive and negative selection of double-positive thymocytes, and in the control of thymocyte reactivity to antigens. IP4 is also a substrate for type I inositol-1,4,5-trisphosphate 5-phosphatase, phosphatidylinositol 4,5-bisphosphate 5-phosphatase A, and skeletal muscle and kidney enriched inositol phosphatase (PMID: 15740635 , 14517551 ).
