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. Involved in TLR3
CC trafficking (PubMed:24791904). {ECO:0000269|PubMed:24791904}.
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 -!- INTERACTION:
CC Q96PC3; Q6PD74: AAGAB; NbExp=3; IntAct=EBI-3923129, EBI-719906;
CC Q96PC3-2; Q6PD74: AAGAB; NbExp=3; IntAct=EBI-12780485, EBI-719906;
CC -!- SUBCELLULAR LOCATION: Golgi apparatus. Cytoplasmic vesicle membrane;
CC Peripheral membrane protein; Cytoplasmic side. Membrane, clathrin-
CC coated pit. Note=Component of the coat surrounding the cytoplasmic face
CC of coated vesicles located at the Golgi complex.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=4;
CC Name=1;
CC IsoId=Q96PC3-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q96PC3-2; Sequence=VSP_015944;
CC Name=4;
CC IsoId=Q96PC3-4; Sequence=VSP_040384;
CC Name=3;
CC IsoId=Q96PC3-3; Sequence=VSP_015942, VSP_015943;
CC -!- TISSUE SPECIFICITY: Widely expressed.
CC -!- DISEASE: Psoriasis 15, pustular (PSORS15) [MIM:616106]: A form of
CC pustular psoriasis, a life-threatening disease defined by repeated
CC flares of sudden onset consisting of diffuse erythematous skin eruption
CC characterized by rapid coverage with pustules, high-grade fever,
CC asthenia, marked leukocytosis, and elevated serum levels of C-reactive
CC protein. {ECO:0000269|PubMed:24791904}. Note=Disease susceptibility is
CC associated with variants affecting the gene represented in this entry.
CC -!- MISCELLANEOUS: [Isoform 2]: May be produced at very low levels due to a
CC premature stop codon in the mRNA, leading to nonsense-mediated mRNA
CC decay. {ECO:0000305}.
CC -!- MISCELLANEOUS: [Isoform 3]: May be produced at very low levels due to a
CC premature stop codon in the mRNA, leading to nonsense-mediated mRNA
CC decay. {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the adaptor complexes small subunit family.
CC {ECO:0000305}.
