What is the official name of the DNAJC5 gene?
The official name of this gene is “DnaJ (Hsp40) homolog, subfamily C, member 5.”
DNAJC5 is the gene's official symbol. The DNAJC5 gene is also known by other names, listed below.
Read more about gene names and symbols on the About page.
What is the normal function of the DNAJC5 gene?
The DNAJC5 provides instructions for making a protein called cysteine string protein alpha (CSPα). This protein is found in the brain, where it plays a role in the transmission of nerve impulses. CSPα helps sac-like structures called synaptic vesicles attach to nerve cells. Synaptic vesicles contain chemical messengers that transmit signals from one nerve cell to another.
Researchers suspect that CSPα may also help repair proteins that are involved in the transmission of nerve impulses by re-folding any that have the incorrect 3-dimensional shape.
Does the DNAJC5 gene share characteristics with other genes?
The DNAJC5 gene belongs to a family of genes called DNAJ (heat shock proteins, DNAJ (HSP40)).
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.
