This protein has a molecular mass of approximately 43 kDa. Expression of Kir6.2 occurs in various tissues most notably in pancreatic beta cells cardiac muscle and neuronal tissues. These channels play an important role in cell membrane potential regulation and excitability modulating insulin release and muscle contraction by responding to intracellular levels of ATP and ADP.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nKir6.2 functions by coupling cellular metabolic states to electrical activity via its role in the K-ATP channel complex. This complex integrates Kir6.2 with the sulfonylurea receptor SUR1 or SUR2 forming an important connection between cellular metabolism and membrane excitability. Kir6.2 helps manage glucose-induced insulin secretion in pancreatic beta cells contributing to the temporal burst of insulin after meals. Its function in neurons and muscle fibers includes balancing cellular energy levels and physiological processes such as neurotransmitter release and muscle contraction.\u003cbr\u003e\nPathways\u003cbr\u003e\nKir6.2 plays a significant role in insulin secretion and cardiac muscle contraction pathways. It interacts closely with various proteins including SUR1 in the insulin release pathway and SUR2 in cardiovascular regulation. The activity of Kir6.2 links it with processes such as glucose-stimulated insulin secretion where its modulation significantly impacts the entry of calcium ions through voltage-dependent calcium channels further altering the exocytosis of insulin granules. The reactivity to intracellular ATP levels means Kir6.2 acts as a metabolic sensor influencing these pathways accordingly.\u003cbr\u003e\nKir6.2 is linked to conditions such as neonatal diabetes mellitus and congenital hyperinsulinism. Mutations in the gene encoding Kir6.2 can disrupt normal K-ATP channel functioning leading to these diseases. In neonatal diabetes Kir6.2 alterations impair insulin secretion due to disrupted ATP binding or channel closure while in congenital hyperinsulinism dysfunction of Kir6.2 in hyperactive channels results in excessive insulin production. This exposes strong connections with proteins like insulin within these conditions highlighting its important influence on glucose metabolism and energy homeostasis.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46845211082921,"sku":"ab264735","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/ar\/products\/abcam-ab264735","provider":"Iright","version":"1.0","type":"link"}
