Protein Structure

UniProt Annotation

Function

Regulates integrin internalization and recycling, but does not influence the traffic of endosomally translocated receptors in general. As a result, may regulate cell adhesion and migration. During the mitosis of adherent cells, controls the endosomal trafficking of integrins which is required for the successful completion of cytokinesis. {ECO:0000269PubMed:16754960, ECO:0000269PubMed:18804435}.

Subcellular Localization

Endoplasmic reticulum membrane; Lipid- anchor. Golgi apparatus membrane. Early endosome membrane. Cytoplasmic vesicle membrane {ECO:0000250}.
