Protein Structure
|
|
Function |
Phosphatidylinositol 3,4,5-trisphosphate-dependent guanine nucleotide exchange factor (GEF) which plays a role in the activation of Rho GTPases RAC1, RhoA and CDC42. Can regulate cell morphology in cooperation with activated RAC1. Plays a role in Th2 (T helper cells) development and/or activation, perhaps by interfering with ZAP70 signaling. Required for optimal T-cell effector function, lymphocyte homeostasis and the prevention of sytemic autoimmunity (By similarity). {ECO:0000250}.
|
Subcellular Localization |
Cytoplasm {ECO:0000269PubMed:12648457}. Cell membrane {ECO:0000269PubMed:12648457}. Nucleus {ECO:0000269PubMed:12648457}. Note=Recruited to the plasma membrane upon binding phosphatidylinositol 3,4,5-trisphosphate.
|
Disease Associations |
Note=Defects in Def6 results in spontaneous development of a lupus-like syndrome in aging female mice. It is characterized by the accumulation of effector/memory T-cells and IgG B-cells, profound hypergammaglobulinemia, autoantibody production, and glomerulonephritis. {ECO:0000269PubMed:12923183}.
|
Tissue Specificity |
Thymus. {ECO:0000269PubMed:12648457}.
