Domain

Protein Kinase B beta, catalytic domain (IPR034677)

Short name: Akt2

Domain relationships

None.

Description

Protein kinase B beta (PKB-beta), also known as AKT2, is one of three closely related serine/threonine-protein kinases: AKT1/alpha, AKT2/beta and AKT3/gamma. PKBs contain an N-terminal pleckstrin homology (PH) domain and a C-terminal catalytic domain [PMID: 9742206]. PKB-beta is the predominant PKB isoform expressed in insulin-responsive tissues. It plays a critical role in the regulation of glucose homeostasis [PMID: 11387480]. It is also implicated in muscle cell differentiation [PMID: 17565718]. Mice deficient in PKB-beta display normal growth weights but exhibit severe insulin resistance and diabetes, accompanied by lipoatrophy and B-cell failure [PMID: 11387480].
