General annotation (Comments)

Function	IGF-1 leads to the activation of AKT3, which may play a role in regulating cell survival. Capable of phosphorylating several known proteins. Truncated isoform 2/PKB gamma 1 without the second serine phosphorylation site could still be stimulated but to a lesser extent By similarity.
Catalytic activity	ATP + a protein = ADP + a phosphoprotein.
Enzyme regulation	Two specific sites, one in the kinase domain (Thr-305) and the other in the C-terminal regulatory region (Ser-472), need to be phosphorylated for its full activation By similarity.
Subunit structure	Interacts (via PH domain) with TCL1A; this enhances AKT3 phosphorylation and activation By similarity.
Subcellular location	Cytoplasm. Membrane; Peripheral membrane protein. Note: Membrane-associated after cell stimulation leading to its translocation.
Tissue specificity	Isoform 1 is expressed in prostate, testis, uterus and mammary gland and isoform 2 is expressed in prostate, testis and mammary gland.
Domain	Binding of the PH domain to the phosphatidylinositol 3-kinase alpha (PI3K) results in its targeting to the plasma membrane.
Post-translational modification	Phosphorylated upon DNA damage, probably by ATM or ATR By similarity.
Sequence similarities	Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. RAC subfamily. Contains 1 AGC-kinase C-terminal domain. Contains 1 PH domain. Contains 1 protein kinase domain.
