Western Blot Detection of Human and Mouse Dynactin Subunit 2/DCTN2 antibody by Western Blot. View Larger

Detection of Human and Mouse Dynactin Subunit 2/DCTN2 by Western Blot. Western blot shows lysates of human placenta tissue and CTLL-2 mouse cytotoxic T cell line. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human Dynactin Subunit 2/DCTN2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6850) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Dynactin Subunit 2/ DCTN2 at approximately 54 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Dynactin Subunit 2/DCTN2 in HeLa Human Cell Line. Dynactin Subunit 2/DCTN2 was detected in immersion fixed HeLa human cervical epithelial carcinoma cell line using Sheep Anti-Human Dynactin Subunit 2/DCTN2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6850) at 15 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (red; Catalog # NL010) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

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.
