Gene details

HGNC symbol
PRKAA1 
Aliases
AMPK; AMPKa1 
Common name
protein kinase AMP-activated catalytic subunit alpha 1 
Description
The protein encoded by this gene belongs to the ser/thr protein kinase family. It is the catalytic subunit of the 5'-prime-AMP-activated protein kinase (AMPK). AMPK is a cellular energy sensor conserved in all eukaryotic cells. The kinase activity of AMPK is activated by the stimuli that increase the cellular AMP/ATP ratio. AMPK regulates the activities of a number of key metabolic enzymes through phosphorylation. It protects cells from stresses that cause ATP depletion by switching off ATP-consuming biosynthetic pathways. Alternatively spliced transcript variants encoding distinct isoforms have been observed.

Study Design
A two-stage case-control study was performed to identify the association between longevity and variation of in homeostasis regulation pathway genes. 317 SNPs in 104 genes were analyzed in 78 cases (≥90 years, median age 98 years, 42 females) and 71 controls (<90 years, median age 67 years, 32 females) in stage 1. Then, 31 candidate SNPs identified in stage 1 (π markers = 0.1) were analyzed in an independent sample composed by 288 cases (≥90 years, median age 92 years, 163 females) and 554 controls (<90 years, median age 67 years, 277 females).
Conclusions
After adjustment for multiple testing, no significant association was identified between various SNPs and longevity.
