Protein Structure
UniProt Annotation
Function In addition to accelerate GTP gamma S binding by ARFs of all three classes, it appears to function preferentially as a guanine nucleotide exchange protein for ARF6, mediating internalisation of beta-1 integrin. {ECO:0000269PubMed:11226253, ECO:0000269PubMed:16461286}.
Subcellular Localization Cytoplasm {ECO:0000269PubMed:11226253}. Nucleus {ECO:0000269PubMed:11226253}. Note=At steady state, may be preferentially cytosolic.
Disease Associations
Tissue Specificity Expressed in brain, ovary, heart, lung, liver, kidney and leukocytes. Moderate expression was also detected in lung, skeletal muscle, placenta, small intestine, pancreas, spleen and testis. {ECO:0000269PubMed:11226253, ECO:0000269PubMed:9872452}.
