Predicted to enable protein kinase activator activity and protein-macromolecule adaptor activity. Involved in dauer larval development; determination of adult lifespan; and regulation of autophagosome assembly. Part of TORC1 complex. Expressed in several structures, including body wall musculature; excretory cell; hermaphrodite distal tip cell; intestine; and pharyngeal muscle cell. Human ortholog(s) of this gene implicated in nicotine dependence. Is an ortholog of human RPTOR (regulatory associated protein of MTOR complex 1).
