Detection of Human and Mouse Dynactin Subunit 1/DCTN1 by Western Blot. Western blot shows lysates of SH‑SY5Y human neuroblastoma cell line and Neuro‑2A mouse neuroblastoma cell line. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human/Mouse Dynactin Subunit 1/DCTN1 Monoclonal Antibody (Catalog # MAB6657) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (HAF018). A specific band was detected for Dynactin Subunit 1/DCTN1 at approximately 150 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.

Background: Dynactin Subunit 1/DCTN1

Dynactin subunit 1 (DCTN1; also DAP-150, p150-1A and p150glued) is a 140-150 kDa member of the dynactin 150 kDa subunit family of proteins. It is a noncovalently-linked homodimer that represents the largest subunit of the neuronal dynactin complex. DCTN1 serves as a bridge that binds dynein to microtubules. This facilitates the transport of molecules along microtubules by the motor molecule dynein. Human DCTN1 is 1278 amino acids (aa) in length. It possesses an N‑terminal microtubule-association region that shows a CAP-Gly domain (aa 48-90) plus a BMBD segment (aa 115-155), and two coiled-coil domains that mediate dimerization (aa 213-547 and 943-1049). There are multiple splice variants. Two are 150 kDa in size; one is widely expressed (p150-1B) and shows a deletion of aa 132‑151, while a second is rare (p150-1AB) and shows a deletion of aa 132‑138. A third variant is 135 kDa in size and possesses a four aa substitution for aa 1-138. Other splice forms possess alternative start sites at Met19 and Met265 that may be coupled to a deletion of aa 1066‑1070 and/or a 42 aa substitution for aa 1066‑1278. Over aa 1145-1278, human DCTN1 shares 97% and 93% aa identity with mouse and rat DCTN1, respectively.
