What is the official name of the CNBP gene?
The official name of this gene is “CCHC-type zinc finger, nucleic acid binding protein.”
CNBP is the gene's official symbol. The CNBP gene is also known by other names, listed below.

What is the normal function of the CNBP gene?
The CNBP gene (also known as ZNF9) provides instructions for making a protein called CCHC-type zinc finger, nucleic acid binding protein. This protein has seven regions, called zinc finger domains, which are thought to attach (bind) to specific sites on DNA and its chemical cousin, RNA.
The CNBP protein is found in many of the body's tissues, but it is most abundant in the heart and in muscles used for movement (skeletal muscles). Although the exact function of this protein is unclear, it appears to regulate the activity of other genes. The CNBP protein is necessary for normal embryonic development.
One region of the CNBP gene contains a segment of four DNA building blocks (nucleotides) that is repeated multiple times. This sequence, which is written as CCTG, is called a tetranucleotide repeat. In most people, the CCTG sequence is repeated fewer than 26 times.
Does the CNBP gene share characteristics with other genes?
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.

Where is the CNBP gene located?
Cytogenetic Location: 3q21
Molecular Location on chromosome 3: base pairs 129,167,815 to 129,183,967
(Homo sapiens Annotation Release 107, GRCh38.p2) (
The CNBP gene is located on the long (q) arm of chromosome 3 at position 21.
More precisely, the CNBP gene is located from base pair 129,167,815 to base pair 129,183,967 on chromosome 3.
