Summary: Predicted to enable GTP-dependent protein binding activity and protein phosphatase binding activity. Involved in anterograde synaptic vesicle transport and synaptic vesicle budding from endosome. Acts upstream of or within with a negative effect on mRNA transcription by RNA polymerase II and regulation of catalytic activity. Acts upstream of or within several processes, including animal organ development; establishment of protein localization to organelle; and vesicle organization. Predicted to be located in trans-Golgi network. Predicted to be part of AP-3 adaptor complex and clathrin adaptor complex. Used to study Hermansky-Pudlak syndrome 2 and platelet storage pool deficiency. Human ortholog(s) of this gene implicated in Hermansky-Pudlak syndrome; Hermansky-Pudlak syndrome 2; interstitial lung disease; neutropenia; and pulmonary fibrosis. Orthologous to human AP3B1 (adaptor related protein complex 3 subunit beta 1). [provided by Alliance of Genome Resources, Apr 2022]

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.
