Zinc Finger Protein 187 (ZNF187)

SRE-ZBP, a previously unidentified SRE-binding protein. SRE-ZBP is a member of the C2H2 zinc finger family of proteins exemplified by TFIIIA and the Drosophila Krüppel protein. The seven tandemly repeated zinc finger motifs in SRE-ZBP are sufficient for high-affinity binding to the SRE. SRE-ZBP is a nuclear protein and identify a candidate cellular protein encoded by the SRE-ZBP gene.SRE-ZBP activity may be subject to posttranslational regulation. Like c-fos mRNA, SRE-ZBP mRNA is serum inducible in HeLa cells, but with slower kinetics. The role of SRE-ZBP in the regulation of c-fos transcription remains unestablished, but this protein binds to a region of the SRE where mutations lead to derepression.
