Anti-DCTN2 (Dynactin Subunit 2, Dynactin Complex 50kD Subunit, DCTN-50, 50kD Dynein-associated Polyp

DCTN2 (Dynactin2? also 50kD dyneinassociated polypeptide and p50 dynamitin) is a 50kD intracellular member of the dynactin subunit 2 family of phosphoproteins. It is ubiquitously expressed and serves to stabilize the dynactin complex of 11 different proteins. This complex is an obligate cofactor of dynein and kinesin motors, which position the mitotic spindle for cell division, and move vesicles within the cell. Human DCTN2 is 401aa in length. It contains three coiled coil regions (aa99-132, 214-244 and 379-399), two potential phosphorylation sites (Ser83 and Tyr86), and one acetylation site at Ala2. The first two coiledcoil regions contribute to oligomerization, while aa191 are essential for dynactin regulation. Potential isoform variants utilize either a five or two aa insertion after Ala35, an alternative start site at Met88, and a 21aa substitution for aa118-401. Over aa277-401, human DCTN2 shares 95% aa identity with mouse DCTN2. Applications: Suitable for use in Immunocytochemistry and Western Blot. Other applications not tested.
