text	localized in both the nucleus and nuclear membrane

basic FUNCTION	AKT is a key regulator for cell growth, cell survival and metabolic insulin action
	involved in the regulation of diverse cellular functions such as cell proliferation, energy metabolism, and apoptosis
	AKT2 and AKT3 play an important role in the viability of human malignant glioma cells
	may oppose AKT1 in lung tumorigenesis and lung tumor progression
	AKT1 and AKT3 are essential for the proliferation of reprogrammed cells

CELLULAR PROCESS	cell life, proliferation/growth
	cell life, antiapoptosis

PHYSIOLOGICAL PROCESS

text	survival of lymphoid and other cell types

PATHWAY

metabolism

signaling

central role of PI3K/AKT signaling in vascular, limb and brain development

a component

INTERACTION

DNA

RNA

small molecule

protein	enhanced AKT2 or AKT3 activation also promotes reprogramming and coordinates with LIF to activate STAT3
	AKT3 is likely a regulator of mitochondrial dynamics in the vasculature via regulation of XPO1-dependent nuclear export

cell & other

REGULATION

activated by	growth factors via PI3K (phosphatidyl inositol 3-kinase) binding to PH domain in the antiapoptotic PI3K pathway induced by insulin growth factor 1, and maybe other
	coactivated by TCL1
