Chem. 277:8140-8145(2002). CC -!- FUNCTION: May play a role in the recruitment of beta-1 integrins CC to the focal contacts during integrin-dependent cell adhesion. CC Isoform 2 does not bind the integrin cytoplasmic domain-associated CC protein-1. CC -!- SUBUNIT: Interacts specifically with the beta-1 integrin CC cytoplasmic domain-associated protein-1. CC -!- SUBCELLULAR LOCATION: Cytoplasmic. CC -!- ALTERNATIVE PRODUCTS: CC Event=Alternative splicing; Named isoforms=2; CC Name=1; Synonyms=ICAP1-alpha; CC IsoId=O14713-1; Sequence=Displayed; CC Name=2; Synonyms=ICAP1-beta; CC IsoId=O14713-2; Sequence=VSP_003898; CC -!- TISSUE SPECIFICITY: Expressed in intestine, colon, testis, ovary, CC thymus, spleen and prostate. CC -!- PTM: Isoform 1 appears to be phosphorylated. The degree of CC phosphorylation is regulated by integrin-dependent cell-matrix CC interaction. CC -!- SIMILARITY: Contains 1 PID domain.
