Summary: Enables molecular adaptor activity. Involved in anterograde synaptic vesicle transport and neuron projection development. Acts upstream of or within several processes, including establishment of protein localization; glutamine family amino acid metabolic process; and limbic system development. Located in endosome. Part of BLOC-1 complex and filamentous actin. Is active in several cellular components, including focal adhesion; microvesicle; and stress fiber. Is expressed in brain; spinal cord; and thoracic ganglion. Used to study Hermansky-Pudlak syndrome 9; platelet storage pool deficiency; and pulmonary emphysema. Human ortholog(s) of this gene implicated in Hermansky-Pudlak syndrome 9. Orthologous to human BLOC1S6 (biogenesis of lysosomal organelles complex 1 subunit 6).

This study analyzed the plasma lipid profiles of three HPS mutant mice, pa (Hps9 (-/-)), ru (Hps6 (-/-)), ep (Hps1 (-/-)), and wild-type (WT) mice. The findings may provide clues to explain why different HPS mutant mice exhibit distinct anti-atherosclerotic or atherogenic effects after being exposed to high-cholesterol diets.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
