gamma2 AMPK activation downregulates fundamental sinoatrial cell pacemaker mechanisms to lower heart rate, including sarcolemmal hyperpolarization-activated current (I f) and ryanodine receptor-derived diastolic local subsarcolemmal Ca(2+) release. In contrast, loss of gamma2 AMPK induces a reciprocal phenotype of increased heart rate, and prevents the adaptive intrinsic bradycardia of endurance training.
Title: Mammalian γ2 AMPK regulates intrinsic heart rate.
gamma2-specific AMPK activity was elevated in neonatal FNIP1-deficient myocardium, supporting a role for FNIP1 as a negative regulator of AMPK.
Title: Mutation of Fnip1 is associated with B-cell deficiency, cardiomyopathy, and elevated AMPK activity.
Increased AMPK-gamma2 activation is required to protect against myocardial ischemia/reperfusion injury.
Title: Activation of γ2-AMPK Suppresses Ribosome Biogenesis and Protects Against Myocardial Ischemia/Reperfusion Injury.
mice with chronic AMPK activation, resulting from mutation of the AMPK gamma2 subunit, exhibit ghrelin signaling-dependent hyperphagia, obesity, and impaired pancreatic islet insulin secretion. Humans bearing the homologous mutation manifest a congruent phenotype.
Title: Chronic Activation of γ2 AMPK Induces Obesity and Reduces β Cell Function.
These results demonstrate that expression of AMPK subunit gamma-2(NI) and AMPK subunit gamma-2(RG) mutations at physiological levels can induce beneficial metabolic effects but that this is accompanied by Wolff-Parkinson-White Syndrome syndrome.
Title: Physiological Expression of AMPKγ2RG Mutation Causes Wolff-Parkinson-White Syndrome and Induces Kidney Injury in Mice.
Prkag2 point mutation causes glycogen storage via enhanced insulin sensitivity and AKT activation. It stimulates postnatal cardiomyocyte proliferation by downregulating FoxO. It promotes cardiac hypertrophy via mTOR activation in developed hearts.
Title: Mutation in the γ2-subunit of AMP-activated protein kinase stimulates cardiomyocyte proliferation and hypertrophy independent of glycogen storage.
We have demonstrated that a third AMPK gamma2 variant, gamma2-3B, is increasingly expressed in the developing heart.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
