General description
Phosphatidylinositol 3-kinase p110γ /phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit γ (PIK3CG) gene, with 12 exons spanning 43 kb on genomic DNA, is mapped to human chromosome 7q22.3. PIK3CG belongs to the family of genes coding for enzymes that phosphorylate the 3′-hydroxyl of phosphatidylinositol.
Biochem/physiol Actions
PI 3-kinases have been implicated in diverse cellular responses triggered by mammalian cell surface receptors. Inhibits NF-κB, AP-1, and STAT1α mediated gene expression induced by IFN-γ resulting in inhibition of COX-2 and NOS ll (iNOS) expression.
Phosphatidylinositol 3-kinase p110γ is implicated in the development of eosinophilic inflammation. Thus, inhibition of PI3Kγ expression can be considered as a potential therapeutic method for treating eosinophil-related diseases, including asthma. Knockdown of PIK3CG gene inhibits the PI3K-Akt/PKB signaling pathway, which is essential for tumorigenesis and the progression of colorectal cancers. Mutation in the gene is associated with the development of autistic disorder.

Class I phosphoinositide 3-kinases (PI3Ks) regulate important cellular processes such as mitogenesis, apoptosis, and cytoskeletal functions. They include PI3Kalpha, -beta, and -delta isoforms coupled to receptor tyrosine kinases and a PI3Kgamma isoform activated by receptor-stimulated G proteins. This study examines
