Growth factors and hormones trigger this phosphorylation event, which in turn coordinates cell growth, cell cycle entry, cell migration, and cell survival (1). PTEN reverses this process, and research studies have shown that the PI3K signaling pathway is constitutively activated in human cancers that have loss of function of PTEN (2). PI3Ks are composed of a catalytic subunit (p110) and a regulatory subunit. Various isoforms of the catalytic subunit (p110α, p110β, p110γ, and p110δ) have been isolated, and the regulatory subunits that associate with p110α, p110β, and p110δ are p85α and p85β (3). In contrast, p110γ associates with a p101 regulatory subunit that is unrelated to p85. Furthermore, p110γ is activated by βγ subunits of heterotrimeric G proteins (4). The p101 regulatory subunit binds to Gβγ, released from heterotrimeric G proteins, and recruits bound p110γ catalytic subunit to the plasma membrane, which is required for GPCR-induced PI3Kγ activity (5).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nF730038I15Rik; FOAP-2; p101; p101-PI3K; Phosphatidylinositol 4,5-bisphosphate 3-kinase regulatory subunit; Phosphatidylinositol-4,5-bisphosphate 3-kinase regulatory subunit; Phosphoinositide 3-kinase regulatory subunit 5; phosphoinositide-3-kinase regulatory subunit 5; phosphoinositide-3-kinase, regulatory subunit 5; phosphoinositide-3-kinase, regulatory subunit 5, p101; phosphoinositide-3-kinase, regulatory subunit, polypeptide p101; PI3-kinase p101 subunit; PI3-kinase regulatory subunit 5; PI3R5; PIK3R5; Protein FOAP-2; PtdIns-3-kinase p101; PtdIns-3-kinase regulatory subunit\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M\nSENSITIVITY: Endogenous\nMW (kDa): 101\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46799819735209,"sku":"5569T","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-5569t","provider":"Iright","version":"1.0","type":"link"}
