Kinase allosteric site

The **kinase allosteric site** refers to non-ATP (non-orthosteric) binding regions within protein kinases that can be modulated by small molecules, peptides, or regulatory proteins. These sites are structurally distinct from the active (catalytic) center but communicate with it through conformational changes, enabling selective inhibition or activation of kinase activity. Targeting allosteric sites provides opportunities for greater specificity and the ability to overcome resistance mechanisms associated with traditional ATP-competitive inhibitors. Allosteric regulation is a key facet of kinase biology, underlying their role as cellular switches in signal transduction, cell cycle control, and various disease states
