Phosphatidylinositol 3-kinase age-1;hypothetical protein


Locus: CELE_B0334.8


Wormbase description: age-1 encodes the C. elegans ortholog of the phosphoinositide 3-kinase (PI3K) p110 catalytic subunit; AGE-1, supplied maternally and embryonically, is a central component of the C. elegans insulin-like signaling pathway, lying downstream of the DAF-2/insulin receptor and upstream of both the PDK-1 and AKT-1/AKT-2 kinases and the DAF-16 forkhead type transcription factor, whose negative regulation is the key output of the insulin signaling pathway; in accordance with its role in insulin signaling, AGE-1 activity is required for regulation of metabolism, life span, dauer formation, stress resistance, salt chemotaxis learning, fertility, and embryonic development; although the age-1 expression pattern has not yet been reported, ectopic expression studies indicate that pan-neuronal age-1 expression is sufficient to rescue life-span defects, while neuronal, intestinal, or muscle expression can partially rescue dauer formation, and neuronal or muscle expression can rescue metabolic defects.

Serine/threonine-protein kinase sgk-1


Locus: CELE_W10G6.2


Wormbase description: sgk-1 encodes a serine/threonine protein kinase that is orthologous to the mammalian serum- and glucocorticoid-inducible kinases (SGKs); in C. elegans, sgk-1 activity is required for normal egg laying, generation time, stress response, and adult life span; SGK-1 forms a complex with the AKT kinases with which it functions in parallel to mediate certain aspects of DAF-2/insulin-signaling; SGK-1 phosphorylates DAF-16 in vitro in a manner strictly dependent upon pdk-1 which encodes a 3-phosphoinositide-dependent kinase; an SGK-1::GFP fusion protein is expressed beginning in late embryonic stages and in larvae is seen in sensory and motor neurons as well as in the intestine; in neurons SGK-1::GFP localizes to the cytoplasm and the nucleus, while in the intestine SGK-1::GFP is found exclusively in the cytoplasm.
