Controlling gene expression through five zinc finger domains of ZNF18.

ABSTRACT: Zinc finger (ZF) proteins are the most abundant transcription factors in vertebrates, and they regulate gene expression through interactions with cis-acting elements. ZF domains selectively recognize specific sequences to accelerate or repress target genes. Zinc finger protein 18 (ZNF18) contains five CX₂CX₁₂HX₃H-type ZFs at the C-terminus, which are expressed in the brain and other organs of the biological system. Bioinformatic study proposed that cyclin-dependent kinase 1 (CDK1) is in the signaling cascade of ZNF18; although experimental evidence has not yet been reported. In this study, we expressed and purified ZNF18(ZF1-5), five ZF domains from ZNF18, and investigated metal binding specificity and promoter interactions. ZNF18(ZF1-5) has specific coordi
