Protein Structure
UniProt Annotation
Function Guanine nucleotide exchange factor (GEF) for RAB35. Promotes the exchange of GDP to GTP, converting inactive GDP-bound RAB35 into its active GTP-bound form. May play a role in clathrin- mediated endocytosis. {ECO:0000269PubMed:20154091, ECO:0000269PubMed:20937701}.
Subcellular Localization Cytoplasm, cytosol {ECO:0000250}. Cytoplasmic vesicle, clathrin-coated vesicle {ECO:0000250}.
Disease Associations
Tissue Specificity Highly expressed in dendritic and natural killer cells and at lower levels in other myeloid lineage cells and in pituitary. Significantly up-regulated in effector memory T- cells as compared with naive T-cells. {ECO:0000269PubMed:20032318}.
