Phosphoinositol signalling pathway
WebThe phosphoinositide 3-kinase (PI3K) pathway, a critical signal transduction system linking oncogenes and multiple receptor classes to many essential cellular functions, is perhaps the most commonly activated signaling pathway in human cancer. This pathway thus presents both an opportunity and a challenge for cancer therapy. IP3, DAG, and Ca are second messengers in the phosphoinositol pathway. The pathway begins with the binding of extracellular primary messengers such as epinephrine, acetylcholine, and hormones AGT, GnRH, GHRH, oxytocin, and TRH, to their respective receptors. Epinephrine binds to the α1 GTPase Protein Coupled Receptor (GPCR) and acetylcholine binds to M1 and M2 GPCR.

WebApr 1, 2009 · The phosphoinositol signaling cascade mediated by G protein activation of PLC-B is one of the most extensively studied pathways in BPD research (Figure 3A). The direct inhibition of IMPase and IPPase by lithium suggests that it may decrease the bioavailability of myoinositol. WebThe protein receptor phosphoinositol kinase A (RpkA) is a seven-membrane-spanning domain protein. Given the apparent role of a G protein in the signaling pathway associated with the development of Dictyostelium from a single-cell to a multicellular organism it is reasonable to investigate whether RpkA plays a part in the starvation signal pathway.
