Summary: Predicted to enable protein kinase binding activity. Predicted to contribute to AMP-activated protein kinase activity. Involved in positive regulation of cold-induced thermogenesis. Predicted to be located in apical plasma membrane. Predicted to be part of cAMP-dependent protein kinase complex and nucleotide-activated protein kinase complex. Predicted to be active in cytoplasm and nucleus. Is expressed in several structures, including alimentary system; cardiovascular system; gallbladder; genitourinary system; and nervous system. Orthologous to human PRKAB2 (protein kinase AMP-activated non-catalytic subunit beta 2). [provided by Alliance of Genome Resources, Dec 2024]

these data indicate that increased expression of AMPKbeta2 is an important feature of efficient adipogenesis.
Title: AMP-activated protein kinase complexes containing the β2 regulatory subunit are up-regulated during and contribute to adipogenesis.
the evidence indicates that AMPK is sufficient but not essential for the maintenance of DAPC expression in skeletal muscle, yet it is required for preserving extrasynaptic utrophin levels in slow oxidative muscles.
Title: The role of AMP-activated protein kinase in the expression of the dystrophin-associated protein complex in skeletal muscle.
AMPK directly relaxes vascular smooth muscle cell by a decrease of [Ca(2+)]i. This is achieved by calcium sequestration via SERCA activation, as well as activation of BKCa channels.

The beta2 subunit plays an important role in regulating glucose, glycogen, and lipid metabolism during metabolic stress. beta2 mutant animals failed to maintain euglycemia and muscle ATP levels during fasting.
Title: The AMPK β2 subunit is required for energy homeostasis during metabolic stress.
Data show that beta1beta2M-KO mice are physically inactive and have a drastically impaired capacity for treadmill running that is associated with reductions in skeletal muscle mitochondrial content.

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.
