Human DOCK2 Antibody

DOCK2 (Dedicator of cytokinesis protein 2) is a member of the DOCK-A family, DOCK180 superfamily of proteins. Its predicted molecular weight is 210 kDa, although it may run approximately at 190 kDa in SDS-PAGE. It is found in hematopoietic cell types, and regulates the activity of the GTPases Rac-1 and -2. Human DOCK2 is 1830 amino acids (aa) in length. It contains one SH3 domain (aa 8‑69), a DHR-1 region that localizes DOCK2 to the plasma membrane (aa 420‑662), and a DHR-2 domain that binds to nucleotide-free GTPases and shows GEF activity (aa 1115‑1621). There are two isoform variants, one that shows a 38 aa substitution for Tyr1405, and a second that shows a start site at Met450 with accompanying deletions of aa 462‑494 and 630‑766, and a 22 aa substitution for aa 934‑1830. Over aa 420‑642, human DOCK2 shares 96% aa identity to mouse DOCK2.
