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.

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.
