Predicted to enable protein kinase activator activity. Acts upstream of or within actin cytoskeleton organization; positive regulation of neuron projection development; and positive regulation of protein phosphorylation. Located in cytoplasm and neuron projection terminus. Is expressed in several structures, including alimentary system; brain; cardiovascular system; genitourinary system; and integumental system. Orthologous to human MOB2 (MOB kinase activator 2). [provided by Alliance of Genome Resources, Apr 2022]
