At least four isoforms of ZBTB4 are known to exist, this antibody will only recognize the longest isoform. This antibody is predicted to not cross-react with other ZBTB protein family members.
Purification
ZBTB4 Antibody is affinity chromatography purified via peptide column.
Immunogen
ZBTB4 antibody was raised against a 18 amino acid synthetic peptide near the carboxy terminus of human ZBTB4. The immunogen is located within amino acids 790 - 840 of ZBTB4.

(Zinc Finger and BTB Domain Containing 4 (ZBTB4))
ZBTB4 Antibody: The ZBTB family of proteins is comprised of diverse zinc finger proteins that also contain a BTB (BR-C, ttk and bab) domain. Similar to Kaiso, a zinc-finger containing protein that can bind methylated CpGs, ZBTB4 can also bind methylated DNA and repress transcription. ZBTB4 has been shown to associate with the Sin3/histone deacetylase co-repressor and repress expression of P21CIP1 as part of a heterodimeric complex with Miz1. In cultured cells, depletion of ZBTB4 promotes cell cycle arrest in response to p53 activation and suppresses apoptosis through regulation of P21CIP1, suggesting that ZBTB4 is a critical determinant of the cellular response to p53 activation. HIPK2, a kinase that is involved in cellular proliferation and survival, phosphorylates and down-regulates ZBTB4 under normal cell growth conditions, this degradation increases with DNA damage.
