DHR1 domain

DHR1 (DOCK homology region 1), also known as CZH1 or Docker1, is a protein domain of approximately 200–250 amino acids that is present in the DOCK family of signalling proteins.^[1] This domain binds phospholipids and so may assist in recruitment to cellular membranes.^[2] There is evidence that this domain may also mediate protein–protein interactions.^[3]
