Gene ID: 8546 | Gene type: protein coding

About AP3B1

Cytogenetic location: 5q14.1 Genomic coordinates (GRCh38): 5:78,000,522-78,294,698 (from NCBI)

This gene has 29 transcripts (splice variants), 226 orthologues, 4 paralogues and is associated with 3 phenotypes. Ubiquitous expression in thyroid (RPKM 10.7), colon (RPKM 8.6) and 25 other tissues.

Summary

This gene encodes a protein that may play a role in organelle biogenesis associated with melanosomes, platelet dense granules, and lysosomes. The encoded protein is part of the heterotetrameric AP-3 protein complex which interacts with the scaffolding protein clathrin. Mutations in this gene are associated with Hermansky-Pudlak syndrome type 2. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2012]
