chromosome 1

Chromosome 1 is the largest human chromosome. It represents approximately 8% of the total DNA in cells.

Summary:Gene examples of chromosome 1:
  • autosome
  • large sized chromosome
  • about 247.000.000 base pairs
  • 2782 known genes
The PARK7 gene provides instructions for making a protein called DJ-1. The DJ-1 protein has several functions like protecting the cells, particularly brain cells, from oxidative stress or to disarm damaged or unwanted proteins as a chaperone molecule. Mutations in the PARK7 gene cause early-onset Parkinson disease with a loss of dopamine-producing nerve cells as a characteristic feature.The DIRAS3 gene: The proteine encoded by this gene occurs in normal ovarian and breast epithelial cells and appears to be a putative tumor suppressor gene. Mutations in this gene can cause breast and ovarian cancers.
