CpG-binding protein (CGBP) also known as CXXC-type zinc finger protein 1 (CXXC1) or PHD finger and CXXC domain-containing protein 1 (PCCX1) is a
protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, res ...
that in humans is encoded by the ''CXXC1''
gene
In biology, the word gene (from , ; "... Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a b ...
.
Proteins that contain a CXXC motif within their DNA-binding domain, such as CXXC1, recognize
CpG sequences and regulate
gene expression.
