DEPDC1B and cancer: The DEPDC1B antibody (HPA072558) recognizes a band of the correct molecular weight for DEPDC1B at approximately 61 kDa on Western blots of proteins from mouse myoblasts (Figure S3) and is located in the nucleus in various cancer cell lines.37 However, DEPDC1B is often reported to also be located at the cell membrane.1, 3, 6 Interestingly, when we overexpressed a V5‐tagged version of DEPDC1B in mouse myoblasts, we found clear membrane localization (Figure S2).
