Predicted to enable actin filament binding activity. Predicted to be involved in several processes, including cellular response to amino acid starvation; cellular response to glucose starvation; and negative regulation of TORC1 signaling. Predicted to be located in lamellipodium and postsynaptic actin cytoskeleton. Predicted to be part of KICSTOR complex and filamentous actin. Human ortholog(s) of this gene implicated in autosomal recessive intellectual developmental disorder 41. Orthologous to human KPTN (kaptin, actin binding protein); INTERACTS WITH 3-chloropropane-1,2-diol; bisphenol A; cadmium dichloride.
