Protein Information
Name DEF6
Synonyms IBP
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 (By similarity).
Cellular Location Cytoplasm. Cell membrane. Nucleus. Note=Recruited to the plasma membrane upon binding phosphatidylinositol 3,4,5-trisphosphate
Tissue Location Broadly expressed in the immune system and can be detected in T and B-cells.
