Function | Functions as a guanine nucleotide exchange factor (GEF) with specificity for RAB11A and RAB25. Inhibits the auto- and transphosphorylation activity of BTK. Plays a negative regulatory role in BTK-related cytoplasmic signaling in B-cells. May be involved in BCR-induced apoptotic cell death. |
