Summaries for AP1S1 Gene

Entrez Gene Summary for AP1S1 Gene

  • The protein encoded by this gene is part of the clathrin coat assembly complex which links clathrin to receptors in coated vesicles. These vesicles are involved in endocytosis and Golgi processing. This protein, as well as beta-prime-adaptin, gamma-adaptin, and the medium (mu) chain AP47, form the AP-1 assembly protein complex located at the Golgi vesicle. [provided by RefSeq, Jul 2008]

GeneCards Summary for AP1S1 Gene

AP1S1 (Adaptor-Related Protein Complex 1, Sigma 1 Subunit) is a Protein Coding gene. Diseases associated with AP1S1 include mednik syndrome and hiv-1. Among its related pathways are Disease and Class I MHC mediated antigen processing and presentation. GO annotations related to this gene include protein transporter activity. An important paralog of this gene is AP1S2.

UniProtKB/Swiss-Prot for AP1S1 Gene

  • Subunit of clathrin-associated adaptor protein complex 1 that plays a role in protein sorting in the late-Golgi/trans-Golgi network (TGN) and/or endosomes. The AP complexes mediate both the recruitment of clathrin to membranes and the recognition of sorting signals within the cytosolic tails of transmembrane cargo molecules.
