Preparation and Storage

Background: Dynactin Subunit 2/DCTN2

DCTN-2 (Dynactin-2; also 50 kDa dynein-associated polypeptide and p50 dynamitin) is a 50 kDa 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 DCTN-2 is 401 amino acids (aa) in length. It contains three coiled‑coil regions (aa 99-132, 214-244 and 379-399), two potential phosphorylation sites (Ser83 and Tyr86), and one acetylation site at Ala2. The first two coiled‑coil regions contribute to oligomerization, while aa 1-91 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 21 aa substitution for aa 118-401. Over aa 277-401, human DCTN-2 shares 95% aa identity with mouse DCTN-2.
