Summary: Enables small GTPase binding activity. Acts upstream of or within blood coagulation and melanocyte differentiation. Located in cytoplasmic vesicle. Is expressed in midgut and midgut loop. Used to study Hermansky-Pudlak syndrome 4 and platelet storage pool deficiency. Human ortholog(s) of this gene implicated in Hermansky-Pudlak syndrome; Hermansky-Pudlak syndrome 4; and schizophrenia. Orthologous to human HPS4 (HPS4 biogenesis of lysosomal organelles complex 3 subunit 2). [provided by Alliance of Genome Resources, Dec 2024]

VARP and Rab9 Are Dispensable for the Rab32/BLOC-3 Dependent Salmonella Killing.
Title: VARP and Rab9 Are Dispensable for the Rab32/BLOC-3 Dependent Salmonella Killing.
results indicate that activation of Rab32/38 by HPS4 (or BLOC-3) is essential for melanogenesis of cultured melanocytes and that Rab9 likely regulates melanogenesis independently of HPS4
Title: The BLOC-3 subunit HPS4 is required for activation of Rab32/38 GTPases in melanogenesis, but its Rab9 activity is dispensable for melanogenesis.
VAMP7 mediates fusion of BLOC-1-dependent transport carriers with melanosomes, illuminate SNARE recycling from melanosomes as a critical BLOC-3-dependent step.
Title: BLOC-1 and BLOC-3 regulate VAMP7 cycling to and from melanosomes via distinct tubular transport carriers.

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.
