Detection of Human AP‑2 beta by Western Blot. Western blot shows lysates of SH‑SY5Y human neuroblastoma cell line. PVDF membrane was probed with 1 µg/mL of Human AP‑2 beta Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5634) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for AP‑2 beta at approximately 55 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: AP-2 beta
AP-2 beta (Activating enhancer-binding protein 2-beta; also TFAP2B) is a 52 kDa member of the AP-2 family of transcription factors. It is primarily a fetal-expressed protein, being found in renal and skin epithelial cells, as well as neuroblasts plus cells of the facial mesenchyme. In adults, AP-2 beta is expressed in renal epithelium. Human AP-2 beta is 460 amino acids (aa) in length. It contains a transactivation domain (aa 41‑131), a DNA-binding motif (aa 132‑298) and a C-terminal dimerization region (aa 299‑439). SUMOylation occurs on Lys21, adding 15 kDa of MW in SDS-PAGE. AP-2 beta both homodimerizes, and heterodimerizes with AP-2 alpha and -2 gamma. Dimers appear important for facial and limb development.
