Also known as: DRR2
Summary: Enables protein serine/threonine kinase activity. Involved in several processes, including establishment or maintenance of actin cytoskeleton polarity; positive regulation of Rho guanyl-nucleotide exchange factor activity; and positive regulation of Rho protein signal transduction. Located in fungal-type vacuole membrane and plasma membrane. Is extrinsic component of cytoplasmic side of plasma membrane. Part of TORC1 complex and TORC2 complex. Human ortholog(s) of this gene implicated in autosomal dominant polycystic kidney disease; kidney angiomyolipoma; lung disease (multiple); prostate cancer; and type 2 diabetes mellitus. Orthologous to human MTOR (mechanistic target of rapamycin kinase). [provided by Alliance of Genome Resources, Apr 2022]
