a proto-oncogenic guanine nucleotide exchange factors (GEF) of the Dbl family. A GEF for the Rho family of GTP binding proteins. Expressed exclusively in hematopoietic cells. Important in hematopoiesis, playing a role in T-cell and B-cell development and activation. Note: This description may include information from UniProtKB.
Protein type: Guanine nucleotide exchange factor, Rac/Rho; Motility/polarity/chemotaxis
Cellular Component: plasma membrane; cytosol
Molecular Function: protein binding; metal ion binding; guanyl-nucleotide exchange factor activity; Rac guanyl-nucleotide exchange factor activity; phospholipid binding; transcription factor activity
