MGI Phenotype

FUNCTION: The membrane-associated 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. The human 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 multiple transcript variants. [provided by RefSeq, Jul 2015]
PHENOTYPE: Mice homozygous for a null allele display lower serum glucose, enhanced insulin action, growth retardation, hypertension and spontaneous death due to episodic coronary artery vasospasm. Homozygous exon 5 deletion leads to cardiac mitochondrial defects, cardiomyopathy, and early postnatal death. [provided by MGI curators]

Protein Function and Prediction

Abcc9 encodes SUR2, a member of the C-branch of the transport adenosine triphosphatase superfamily and regulatory subunit of ATP-sensitive potassium channels (K_ATP channels) (1;2). K_ATP channels function in responses to cardiac stress, vascular smooth muscle tone, skeletal muscle glucose uptake, neuronal excitability, transmitter release, ischemic preconditioning, and insulin secretion from pancreatic β-cells (3). The pore are octameric complexes comprised of four pore-forming Kir6.2 subunits and four regulatory SUR subunits (1). Mouse Sur2 has 13 transmembrane domains and intracellular Walker A and B ATP-binding domains (4). SUR2 can be alternatively spliced to generate SUR2A and SUR2B, which differ in their C-terminal 42 amino acids (1).

Expression/Localization

Northern blot analysis detected three human SUR2 transcripts (9.4, 7.6, and 5.6 kb); the highest level of the longer transcript is in the heart and skeletal muscle; little to no SUR2 was detected in other tissues (4). In mouse tissues, Sur2 a 9.4 kb transcript was ubiquitously expressed; a 8.6 kb transcript was expressed at high levels in the skeletal muscle and heart (4). Western blot analysis determined that SUR2A is expressed in cardiac and skeletal muscle, while SUR2B is in smooth muscle and some neurons (5).

Background

Mutations in ABCC9 are linked to familial atrial fibrillation 12 [OMIM: 614050; (6)], dilated cardiomyopathy 10 [OMIM: 608569; (7)], and hypertrichotic osteochondrodysplasia [alternatively, Cantu syndrome; OMIM: 239850; (8;9)]. Cantu syndrome is a rare disorder characterized by congenital hypertrichosis, neonatal macrosomia, a distinct osteochondrodysplasia, and cardiomegaly. The hypertrichosis leads to thick scalp hair which extends onto the forehead and to a general increase in body hair.

Abcc9^{tm1Cfb/tm1Cfb}; MGI:2155916

involves: CD-1

Mice homozygous for disruptions in this gene display lower serum glucose, enhanced insulin action, growth retardation and slow postnatal weight gain, hypertension and spontaneous death starting at 6 weeks of age due to episodic coronary artery vasospasm (10).

Abcc9^tm1Cfb/tm1Cf^b; MGI:2155916

Not specified

In this genetic background, homozygotes also exhibit premature death (by 30 weeks), abnormal vasoconstriction, abnormal ST segment, hypertension, and absent glibenclamide-sensitive K_ATP current in aortic smooth muscle cells (11).
