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? (http://ghr.nlm.nih.gov/handbook/howgeneswork/genefamilies) in the Handbook.
How are changes in the PINK1 gene related to health conditions?
- Parkinson disease - caused by mutations in the PINK1 gene
Researchers have identified more than 70 mutations in the PINK1 gene that can cause Parkinson disease, a condition characterized by progressive problems with movement and balance. PINK1 gene mutations are associated with the early-onset form of the disorder, which typically begins before age 50.
Many PINK1 gene mutations alter or eliminate the kinase domain, leading to a loss of protein function. At least one mutation affects the mitochondrial-targeting motif and may disrupt delivery of the protein to mitochondria. With reduced or absent PTEN induced putative kinase 1 activity, mitochondria may malfunction, particularly when cells are stressed. Cells can die if energy is not provided for essential activities. It is unclear how PINK1 gene mutations cause the selective death of nerve cells that characterizes Parkinson disease. The loss of these cells weakens communication between the brain and muscles, and ultimately the brain becomes unable to control muscle movement.
Where is the PINK1 gene located?
Cytogenetic Location: 1p36
Molecular Location on chromosome 1: base pairs 20,633,454 to 20,651,510
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 20,633,454 to base pair 20,651,510 on chromosome 1.
