Proteome Res. 7:1675-1682(2008). CC -!- FUNCTION: Adaptins are components of the adapter complexes which CC link clathrin to receptors in coated vesicles. Clathrin-associated CC protein complexes are believed to interact with the cytoplasmic CC tails of membrane proteins, leading to their selection and CC concentration. AP-2alpha is a subunit of the plasma membrane CC adapter. {ECO:0000269|PubMed:9118220, ECO:0000269|PubMed:9285813}. CC -!- SUBUNIT: Adaptor protein complex 2 (AP-2) is a heterotetramer CC composed of two large adaptins (alpha-type and beta-type CC subunits), a medium adaptin (mu-type subunit AP50) and a small CC adaptin (sigma-type subunit AP17). {ECO:0000250}. CC -!- SUBCELLULAR LOCATION: Cell membrane. Membrane, coated pit; CC Peripheral membrane protein; Cytoplasmic side. Note=Component of CC the coat surrounding the cytoplasmic face of coated vesicles in CC the plasma membrane. CC -!- ALTERNATIVE PRODUCTS: CC Event=Alternative splicing; Named isoforms=2; CC Name=A; CC IsoId=P91926-1; Sequence=Displayed; CC Name=B; CC IsoId=P91926-2; Sequence=VSP_023135; CC Note=No experimental confirmation available.; CC -!- TISSUE SPECIFICITY: Expressed in the Garland cells, imaginal CC disks, adult midgut precursors, the antenno-maxillary complex, the CC endoderm, the fat bodies, and the visceral mesoderm and cells of CC the CNS and PNS including neuroblasts, the presumptive CC stomatogastric nervous system, and the lateral chordotonal sense CC organs. {ECO:0000269|PubMed:9118220, ECO:0000269|PubMed:9285813}. CC -!- RNA EDITING: Modified_positions=207 {ECO:0000269|PubMed:17018572, CC ECO:0000269|Ref.6}; Note=Partially edited. Target of Adar.; CC -!- SIMILARITY: Belongs to the adaptor complexes large subunit family. CC {ECO:0000305}.
