B-Raf domains include the kinase domain - residues 444-721 and Ras-binding domain - residues 153-237. Mutated B-Raf was found in some human cancers<ref>PMID:12460918</ref>.

'''AMP-activated protein kinase''' (AMPK) is a [[nuclear receptor]] which regulates cellular uptake of glucose, β-oxidation of fatty acids and biogenesis of glucose transporter thus playing a role in cellular energy homeostasis by phosphorylating key proteins. In response to low levels of ATP, AMPK activates energy-producing pathways and inhibits energy-consuming pathways. | '''AMP-activated protein kinase''' (AMPK) is a [[nuclear receptor]] which regulates cellular uptake of glucose, β-oxidation of fatty acids and biogenesis of glucose transporter thus playing a role in cellular energy homeostasis by phosphorylating key proteins.
