Metabolite Identification
Common Namemyo-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 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 ).

General function:
Involved in inositol or phosphatidylinositol phosphatase activity
Specific function:
Phosphatidylinositol (PtdIns) phosphatase that specifically hydrolyzes the 5-phosphate of phosphatidylinositol-3,4,5-trisphosphate (PtdIns(3,4,5)P3) to produce PtdIns(3,4)P2, thereby negatively regulating the PI3K (phosphoinositide 3-kinase) pathways. Plays a central role in regulation of PI3K-dependent insulin signaling, although the precise molecular mechanisms and signaling pathways remain unclear. While overexpression reduces both insulin-stimulated MAP kinase and Akt activation, its absence does not affect insulin signaling or GLUT4 trafficking. Confers resistance to dietary obesity. May act by regulating AKT2, but not AKT1, phosphorylation at the plasma membrane. Part of a signaling pathway that regulates actin cytoskeleton remodeling. Required for the maintenance and dynamic remodeling of actin structures as well as in endocytosis, having a major impact on ligand-induced EGFR internalization and degradation. Participates in regulation of cortical and submembraneous actin by hydrolyzing PtdIns(3,4,5)P3 thereby regulating membrane ruffling. Regulates cell adhesion and cell spreading. Required for HGF-mediated lamellipodium formation, cell scattering and spreading. Acts as a negative regulator of EPHA2 receptor endocytosis by inhibiting via PI3K-dependent Rac1 activation. Acts as a regulator of neuritogenesis by regulating PtdIns(3,4,5)P3 level and is required to form an initial protrusive pattern, and later, maintain proper neurite outgrowth. Acts as a negative regulator of the FC-gamma-RIIA receptor (FCGR2A). Mediates signaling from the FC-gamma-RIIB receptor (FCGR2B), playing a central role in terminating signal transduction from activating immune/hematopoietic cell receptor systems. Involved in EGF signaling pathway. Upon stimulation by EGF, it is recruited by EGFR and dephosphorylates PtdIns(3,4,5)P3. Plays a negative role in regulating the PI3K-PKB pathway, possibly by inhibiting PKB activity. Down-regulates Fc-gamma-R-mediated phagocytosis in macrophages independently of INPP5D/SHIP1. In macrophages, down-regulates NF-kappa-B-dependent gene transcription by regulating macrophage colony-stimulating factor (M-CSF)-induced signaling. May also hydrolyze PtdIns(1,3,4,5)P4, and could thus affect the levels of the higher inositol polyphosphates like InsP6.

General function:
Involved in acid phosphatase activity
Specific function:
Acts as a phosphoinositide 5- and phosphoinositide 6-phosphatase and regulates cellular levels of inositol pentakisphosphate (InsP5) and inositol hexakisphosphate (InsP6). Also acts as a 2,3-bisphosphoglycerate 3-phosphatase, by mediating the dephosphorylation of 2,3-bisphosphoglycerate (2,3-BPG) to produce phospho-D-glycerate without formation of 3-phosphoglycerate. May play a role in bone development (endochondral ossification).

General function:
Involved in catalytic activity
Specific function:
Kinase that can phosphorylate various inositol polyphosphate such as Ins(3,4,5,6)P4 or Ins(1,3,4)P3. Phosphorylates Ins(3,4,5,6)P4 at position 1 to form Ins(1,3,4,5,6)P5. This reaction is thought to have regulatory importance, since Ins(3,4,5,6)P4 is an inhibitor of plasma membrane Ca(2+)-activated Cl(-) channels, while Ins(1,3,4,5,6)P5 is not. Also phosphorylates Ins(1,3,4)P3 on O-5 and O-6 to form Ins(1,3,4,6)P4, an essential molecule in the hexakisphosphate (InsP6) pathway. Also acts as an inositol polyphosphate phosphatase that dephosphorylate Ins(1,3,4,5)P4 and Ins(1,3,4,6)P4 to Ins(1,3,4)P3, and Ins(1,3,4,5,6)P5 to Ins(3,4,5,6)P4. May also act as an isomerase that interconverts the inositol tetrakisphosphate isomers Ins(1,3,4,5)P4 and Ins(1,3,4,6)P4 in the presence of ADP and magnesium. Probably acts as the rate-limiting enzyme of the InsP6 pathway. Modifies TNF-alpha-induced apoptosis by interfering with the activation of TNFRSF1A-associated death domain.
