Background: PI 3-Kinase p55 gamma

PI 3-Kinase p55 gamma, also referred to as PI3Kp55 gamma or p55gamma, is a regulatory subunit of phosphatidylinositol 3-kinase (PI 3-Kinase / PI3K) (1). Class 1A PI 3-Kinases are heterodimers consisting of one 110 kDa catalytic subunit (p110 alpha, beta, or delta) and one regulatory subunit (p85 alpha, p85 beta, p55 alpha, p50 alpha, or p55 gamma) (1). The p55 gamma regulatory subunit is encoded by the PIK3R3 gene and is predominantly expressed in the brain (2). Human PI 3 Kinase p55 gamma protein is 461 amino acids (aa) in length with a theoretical molecular weight of ~54 kDa (3). Structurally, PI 3-Kinase p55 gamma contains a proline rich domain (aa 34 - 44) and two Src homology domains (SH2, aa 65 - 160 and 358 - 452) (1,3). In general, Class 1A PI 3-Kinases are activated through the binding of membrane-bound tyrosine kinase receptors, such as insulin-like growth factor 1 (IGF-1) (1,2,4). Activation of PI 3-Kinase results in the phosphorylation of phosphatidyl inositol and a downstream signaling cascade of the AKT/mTOR pathway (2,4). PI 3-Kinase pathway activation results in a number of cellular responses including proliferation, survival, growth, migration, membrane trafficking, and metabolism (2). The PI3-Kinase/AKT/mTOR pathway has been shown to be dysregulated in a number of cancers, largely through loss or inactivation of the tumor suppressor PTEN (4). Furthermore, one study found that anaplastic lymphoma kinase (ALK) promoted cell migration during brain development specifically through the p55 gamma regulatory subunit of PI 3-Kinase (5).
