AP1S3
(redirected from Clathrin assembly protein complex 1 sigma-1C small chain)AP1S3
A gene on chromosome 2q36.1 that encodes a subunit of the trans-Golgi network clathrin-associated protein complex AP-1, which is located at the Golgi vesicle and links clathrin to receptors in coated vesicles. The vesicles are involved in protein sorting in the late-Golgi/trans-Golgi network and/or endosomes; the AP complexes recruit clathrin to membranes and recognise sorting signals within the cytosolic tails of transmembrane cargo molecules.Segen's Medical Dictionary. © 2012 Farlex, Inc.
