PIK3CG Proteins

Protein Information

PIK3CG (p110 gamma) is the sole class IB phosphatidylinositol 3-kinase family member, which along with the class IA family members, generates the important second messenger PIP2. However, unlike the class IA enzymes which signal downstream of receptor tyrosine kinases, PIK3CG primarily signals downstream of GPCRs. The gene product is an enzyme that phosphorylates phosphoinositides on the 3-hydroxyl group of the inositol ring. It is an important modulator of extracellular signals, including those elicited by E-cadherin-mediated cell-cell adhesion, which plays an important role in maintenance of the structural and functional integrity of epithelia. In addition to its role in promoting assembly of adherens junctions, the protein is thought to play a pivotal role in the regulation of cytotoxicity in NK cells. The gene is located in a commonly deleted segment of chromosome 7 previously identified in myeloid leukemias.
