Full Name: Adenylate Kinase 5

Genomic Location: Chromosome 1:77,281,977-77,559,969

Protein Size: 562 amino acids


This gene encodes a member of the adenylate kinase family, which is involved in regulating the adenine nucleotide composition within a cell by catalyzing the reversible transfer of phosphate groups among adenine nucleotides. This member is related to the UMP/CMP kinase of several species. It is located in the cytosol and expressed exclusively in brain.

Linked SNP(s):

  • rs76681500 is linked to AK5, it is located approximately 30,000 bases upstream.
  • Population frequencies are approximately 89% for the reference allele (G) and 11% for the alternate allele (A).
  • Studies suggest the G allele is associated with an increased tendency towards being a night owl.
