ZCCHC gene family

Reviewed October 2010

What are the ZCCHC genes?

Genes in the ZCCHC family provide instructions for making proteins known as CCHC-containing zinc finger proteins. This family is a subset of a much larger group of zinc finger proteins, which are involved in many cellular functions.

Zinc finger proteins each contain one or more short regions called zinc finger domains. These regions include a specific pattern of protein building blocks (amino acids) and one or more charged atoms of zinc (zinc ions). CCHC refers to the particular sequence of the amino acids cysteine and histidine found in proteins in the ZCCHC family. These amino acids fold around a single zinc ion, making the protein very stable and enabling it to attach (bind) firmly to other molecules.

Little is known about the function of CCHC-containing zinc finger proteins. Unlike many other zinc finger proteins, most proteins in this family do not appear to bind to DNA. Instead, studies suggest that they may help regulate interactions between other proteins.

Which genes are included in the ZCCHC gene family?

The HUGO Gene Nomenclature Committee (HGNC) provides an index of gene families ( and their member genes.

Genetics Home Reference summarizes the normal function and health implications of this member of the ZCCHC gene family: CNBP.
