CC   -!- FUNCTION: Subunit of clathrin-associated adaptor protein complex 1 that
CC       plays a role in protein sorting in the late-Golgi/trans-Golgi network
CC       (TGN) and/or endosomes. The AP complexes mediate both the recruitment
CC       of clathrin to membranes and the recognition of sorting signals within
CC       the cytosolic tails of transmembrane cargo molecules.
CC       {ECO:0000269|PubMed:9733768}.
CC   -!- SUBUNIT: Adaptor protein complex 1 (AP-1) is a heterotetramer composed
CC       of two large adaptins (gamma-type subunit AP1G1 and beta-type subunit
CC       AP1B1), a medium adaptin (mu-type subunit AP1M1 or AP1M2) and a small
CC       adaptin (sigma-type subunit AP1S1 or AP1S2 or AP1S3).

CC   -!- DISEASE: MEDNIK syndrome (MEDNIK) [MIM:609313]: A disorder
CC       characterized by erythematous skin lesions and hyperkeratosis, severe
CC       psychomotor retardation, peripheral neuropathy, sensorineural hearing
CC       loss, together with elevated very-long-chain fatty acids and severe
CC       congenital diarrhea. {ECO:0000269|PubMed:19057675}. Note=The disease is
CC       caused by variants affecting the gene represented in this entry.
CC   -!- SIMILARITY: Belongs to the adaptor complexes small subunit family.
