ATP-binding cassette, sub-family C member 9 (ABCC9) also known as sulfonylurea receptor 2 (SUR2) is an ATP-binding cassette transporter that in humans is encoded by the ABCC9 gene. [5] [6]

Function

The protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This protein is a member of the MRP subfamily which is involved in multi-drug resistance. This protein is thought to form ATP-sensitive potassium channels in cardiac, skeletal, and vascular and non-vascular smooth muscle. Protein structure suggests a role as the drug-binding channel-modulating subunit of the extrapancreatic ATP-sensitive potassium channels. Alternative splicing of this gene results in several products, two of which result from differential usage of two terminal exons and one of which results from exon deletion. [7]

Clinical significance

The gene has been associated with dilated cardiomyopathy and Cantú syndrome. [6] [8]

A variant has also been associated with circa 25 minutes more sleep per day in humans; lack thereof has been associated with three hours less sleep per day in fruit flies. [9] [10]

A study involving 12,901 individuals from Iceland demonstrated a link between variants of the ABCC9 gene and higher vocal pitch in both men and women. This discovery establishes ABCC9 as the first identified genetic locus associated with vocal pitch. [11]

An ATP-sensitive potassium channel is a type of potassium channel that is gated by intracellular nucleotides, ATP and ADP. ATP-sensitive potassium channels are composed of Kir6.x-type subunits and sulfonylurea receptor (SUR) subunits, along with additional components. KATP channels are widely distributed in plasma membranes; however some may also be found on subcellular membranes. These latter classes of KATP channels can be classified as being either sarcolemmal ("sarcKATP"), mitochondrial ("mitoKATP"), or nuclear ("nucKATP").

In molecular biology, the sulfonylurea receptors (SUR) are membrane proteins which are the molecular targets of the sulfonylurea class of antidiabetic drugs whose mechanism of action is to promote insulin release from pancreatic beta cells. More specifically, SUR proteins are subunits of the inward-rectifier potassium ion channels Kir6.x. The association of four Kir6.x and four SUR subunits form an ion conducting channel commonly referred to as the KATP channel.
