CC -!- FUNCTION: Akt2-a is one of several closely related serine/threonine-
CC protein kinases known as the AKT kinase, and which regulate many
CC processes including metabolism, proliferation, cell survival, growth
CC and angiogenesis. This is mediated through serine and/or threonine
CC phosphorylation of a range of downstream substrates. Over 100 substrate
CC candidates have been reported so far, but for most of them, no isoform
CC specificity has been reported (By similarity). May be involved in the
CC inhibition of ciliogenesis (By similarity). {ECO:0000250,
CC ECO:0000250|UniProtKB:P31751}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-seryl-[protein] = ADP + H(+) + O-phospho-L-seryl-
CC [protein]; Xref=Rhea:RHEA:17989, Rhea:RHEA-COMP:9863, Rhea:RHEA-

CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-threonyl-[protein] = ADP + H(+) + O-phospho-L-
CC threonyl-[protein]; Xref=Rhea:RHEA:46608, Rhea:RHEA-COMP:11060,

CC ChEBI:CHEBI:30616, ChEBI:CHEBI:61977, ChEBI:CHEBI:456216;
CC EC=2.7.11.1; Evidence={ECO:0000250|UniProtKB:Q60823};
CC -!- ACTIVITY REGULATION: Two specific sites, one in the kinase domain (Thr-
CC 314) and the other in the C-terminal regulatory region (Ser-479), need
CC to be phosphorylated for its full activation. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the protein kinase superfamily. AGC Ser/Thr
CC protein kinase family. RAC subfamily. {ECO:0000305}.
