What is the official name of the DNAJC19 gene?
The official name of this gene is “DnaJ heat shock protein family (Hsp40) member C19.”
DNAJC19 is the gene's official symbol. The DNAJC19 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 DNAJC19 gene?
The DNAJC19 gene provides instructions for producing a protein found in structures called mitochondria, which are the energy-producing centers of cells. While the exact function of the DNAJC19 protein is unclear, researchers believe that it helps transport other proteins into and out of mitochondria. The DNAJC19 protein may also assist in the proper assembly and disassembly of certain proteins.
Does the DNAJC19 gene share characteristics with other genes?
The DNAJC19 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.
