Summary: Predicted to enable GTP-dependent protein binding activity and small GTPase binding activity. Involved in lipid homeostasis; lysosome localization; and protein secretion. Acts upstream of or within blood coagulation; melanocyte differentiation; and organelle organization. Predicted to be located in several cellular components, including endoplasmic reticulum; endosome; and lysosome. Predicted to be part of BLOC-2 complex. Predicted to be active in lysosomal membrane. Used to study Hermansky-Pudlak syndrome 6. Human ortholog(s) of this gene implicated in Hermansky-Pudlak syndrome and Hermansky-Pudlak syndrome 6. Orthologous to human HPS6 (HPS6 biogenesis of lysosomal organelles complex 2 subunit 3). [provided by Alliance of Genome Resources, Apr 2022]

VWF maturation and release are controlled by 2 regulators of Weibel-Palade body biogenesis: exocyst and BLOC-2.
Title: VWF maturation and release are controlled by 2 regulators of Weibel-Palade body biogenesis: exocyst and BLOC-2.
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.
Title: Plasma lipidomic profiling in murine mutants of Hermansky-Pudlak syndrome reveals differential changes in pro- and anti-atherosclerotic lipids.
BLOC-2 subunit HPS6 deficiency affects the tubulation and secretion of von Willebrand factor from mouse endothelial cells
Title: BLOC-2 subunit HPS6 deficiency affects the tubulation and secretion of von Willebrand factor from mouse endothelial cells.
BLOC-2 functions to direct recycling endosomal tubular transport intermediates to maturing melanosomes and thereby promote cargo delivery and optimal pigmentation.
Title: BLOC-2 targets recycling endosomal tubules to melanosomes for cargo delivery.
The product of the Mreg(dsu) locus, melanoregulin (MREG), interacts both with members of BLOC-2 complex and with ocular albinism in regulating melanosome size.
Title: Melanoregulin, product of the dsu locus, links the BLOC-pathway and OA1 in organelle biogenesis.
Data suggest functional links between OCA2 and the BLOC-1, BLOC-2, and AP-3 protein complexes involved in melanosome biogenesis.
Title: Functional interactions between OCA2 and the protein complexes BLOC-1, BLOC-2, and AP-3 inferred from epistatic analyses of mouse coat pigmentation.
The identification of the feeble mutation led to our subsequent observations that AP-3, as well as the BLOC-1 and BLOC-2 are essential for plasmacytoid dendritic cells signaling through TLR7 and TLR9.
Title: Slc15a4, AP-3, and Hermansky-Pudlak syndrome proteins are required for Toll-like receptor signaling in plasmacytoid dendritic cells.

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.
