What is the official name of the PINK1 gene?The official name of this gene is “PTEN induced putative kinase 1.” PINK1 is the gene's official symbol. The PINK1 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 PINK1 gene?The PINK1 gene provides instructions for making a protein called PTEN induced putative kinase 1. This protein is found in cells throughout the body, with highest levels in the heart, muscles, and testes. Within cells, the protein is located in the mitochondria, the energy-producing centers that provide power for cellular activities. The function of PTEN induced putative kinase 1 is not fully understood. It appears to help protect mitochondria from malfunctioning during periods of cellular stress, such as unusually high energy demands. Researchers believe that two specialized regions of PTEN induced putative kinase 1 are essential for the protein to function properly. One region, called the mitochondrial-targeting motif, serves as a delivery address: after the protein is made, this motif helps ensure that it is delivered to the mitochondria. Another region, called the kinase domain, probably carries out the protein's protective function. Does the PINK1 gene share characteristics with other genes?The PINK1 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 PINK1 gene related to health conditions?
Where is the PINK1 gene located?Cytogenetic Location: 1p36 Molecular Location on chromosome 1: base pairs 20,959,947 to 20,978,003 The PINK1 gene is located on the short (p) arm of chromosome 1 at position 36. More precisely, the PINK1 gene is located from base pair 20,959,947 to base pair 20,978,003 on chromosome 1. See How do geneticists indicate the location of a gene? in the Handbook.
