About AP2A1

Cytogenetic location: 19q13.33 Genomic coordinates (GRCh38): 19:49,767,001-49,807,114 (from NCBI)

This gene has 8 transcripts (splice variants), 195 orthologues and 4 paralogues. Broad expression in testis (RPKM 42.9), brain (RPKM 24.7) and 25 other tissues.

Summary

This gene encodes the alpha 1 adaptin subunit of the adaptor protein 2 (AP-2) complex found in clathrin coated vesicles. The AP-2 complex is a heterotetramer consisting of two large adaptins (alpha or beta), a medium adaptin (mu), and a small adaptin (sigma). The complex is part of the protein coat on the cytoplasmic face of coated vesicles which links clathrin to receptors in vesicles. Alternative splicing of this gene results in two transcript variants encoding two different isoforms. A third transcript variant has been described, but its full length nature has not been determined. [provided by RefSeq, Jul 2008]
