znf511 Antibody

What is ZNF511 and why is it important in research?

ZNF511 (zinc finger protein 511) is a 262 amino acid nuclear protein belonging to the Krüppel C2H2-type zinc-finger protein family. It plays a crucial role in transcriptional regulation, which is vital for controlling gene expression and maintaining cellular functions. ZNF511 contains three C2H2-type zinc fingers and is thought to interact with KAP1 protein, thereby recruiting histone-modifying enzymes that influence chromatin structure and gene accessibility. The gene is located on human chromosome 10, which harbors approximately 1,200 genes and accounts for about 4.5% of the human genome. ZNF511's ability to modulate transcriptional activity makes it important for studying various biological processes, including development and cellular response to environmental stimuli .
