Detection of Human ZBTB38 by Western Blot. Western blot shows lysates of RPMI 8226 human multiple myeloma cell line. PVDF membrane was probed with 1 µg/mL of Human ZBTB38 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5784) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for ZBTB38 at approximately 175 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

ZBTB38 (Zinc finger and BTB domain-containing protein 38; also CIBZ and Zenon) is an early member of a family of Kaiso-like DNA binding proteins. Although its predicted MW is 134 kDa, it runs anomalously in SDS-PAGE at 175 kDa. ZBTB38 binds to singly methylated CpG (cytosine-phosphate-guanine) motifs. It is considered a transcriptional repressor that either homodimerizes, or heterodimerizes with ZBTB4, and subsequently interacts with either CtBP-1 or -2 to mediate repression. Human ZBTB38 is 1195 amino acids (aa) in length. It contains a BTB domain (aa 33‑100), an RD2 region (aa 158‑341) and ten C2H2-type zinc finger domains (aa 342‑1147). There is one potential alternate start site at Met595. Over aa 1‑232, human ZBTB38 shares 96% aa identity with mouse ZBTB38.
