What is the official name of the PARK7 gene?The official name of this gene is “parkinson protein 7.” PARK7 is the gene's official symbol. The PARK7 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 PARK7 gene?The PARK7 gene provides instructions for making the DJ-1 protein. This protein is found in many tissues and organs, including the brain. Studies indicate that the DJ-1 protein has several functions, although none are fully understood. One of the protein's functions may be to help protect cells, particularly brain cells, from oxidative stress. Oxidative stress occurs when unstable molecules called free radicals accumulate to levels that can damage or kill cells. Additionally, the DJ-1 protein may serve as a chaperone molecule that helps fold newly produced proteins into the proper 3-dimensional shape and helps refold damaged proteins. Like other chaperone molecules, the DJ-1 protein may assist in delivering selected proteins to proteasomes, which are structures within cells that break down unneeded molecules. Researchers suggest that the DJ-1 protein may also play a role in activities that produce and process RNA, a chemical cousin of DNA. Does the PARK7 gene share characteristics with other genes?The PARK7 gene belongs to a family of genes called PARK (Parkinson disease). 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. How are changes in the PARK7 gene related to health conditions?
Where is the PARK7 gene located?Cytogenetic Location: 1p36.23 Molecular Location on chromosome 1: base pairs 8,021,713 to 8,045,341 The PARK7 gene is located on the short (p) arm of chromosome 1 at position 36.23. More precisely, the PARK7 gene is located from base pair 8,021,713 to base pair 8,045,341 on chromosome 1. See How do geneticists indicate the location of a gene? in the Handbook.
