Predicted to enable protein serine/threonine kinase activator activity. Predicted to be involved in TORC1 signaling; positive regulation of TOR signaling; and regulation of actin cytoskeleton organization. Predicted to act upstream of or within positive regulation of actin filament polymerization; positive regulation of peptidyl-tyrosine phosphorylation; and regulation of GTPase activity. Located in cytosol. Orthologous to human MLST8 (MTOR associated protein, LST8 homolog). [provided by Alliance of Genome Resources, Apr 2022]
