Predicted to enable actin filament binding activity and protein homodimerization activity. Predicted to be involved in several processes, including cellular amino acid metabolic process; establishment of vesicle localization; and limbic system development. Predicted to act upstream of or within several processes, including melanocyte differentiation; positive regulation of natural killer cell activation; and secretion of lysosomal enzymes. Predicted to be located in ciliary basal body and endosome. Predicted to be part of BLOC-1 complex. Predicted to be active in transport vesicle. Predicted to be extrinsic component of membrane. Human ortholog(s) of this gene implicated in Hermansky-Pudlak syndrome 9. Orthologous to human BLOC1S6 (biogenesis of lysosomal organelles complex 1 subunit 6).
