General annotation (Comments)
| Function | Subunit of ATP-sensitive potassium channels (KATP). Can form cardiac and smooth muscle-type KATP channels with KCNJ11. KCNJ11 forms the channel pore while ABCC9 is required for activation and regulation. Ref.3 Ref.4 |
| Subunit structure | Interacts with KCNJ11. Ref.3 |
| Subcellular location | Membrane; Multi-pass membrane protein Potential. |
| Involvement in disease | Cardiomyopathy, dilated 1O (CMD1O) [MIM:608569]: A disorder characterized by ventricular dilation and impaired systolic function, resulting in congestive heart failure and arrhythmia. Patients are at risk of premature death. Familial atrial fibrillation 12 (ATFB12) [MIM:614050]: A familial form of atrial fibrillation, a common sustained cardiac rhythm disturbance. Atrial fibrillation is characterized by disorganized atrial electrical activity and ineffective atrial contraction promoting blood stasis in the atria and reduces ventricular filling. It can result in palpitations, syncope, thromboembolic stroke, and congestive heart failure. Hypertrichotic osteochondrodysplasia (HTOCD) [MIM:239850]: 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 a general increase in body hair. In addition, macrocephaly and coarse facial features, including a broad nasal bridge, epicanthal folds, a wide mouth, and full lips, can be suggestive of a storage disorder. About half of affected individuals are macrosomic and edematous at birth, whereas in childhood they usually have a muscular appearance with little subcutaneous fat. Thickened calvarium, narrow thorax, wide ribs, flattened or ovoid vertebral bodies, coxa valga, osteopenia, enlarged medullary canals, and metaphyseal widening of long bones have been reported. Cardiac manifestations such as patent ductus arteriosus, ventricular hypertrophy, pulmonary hypertension, and pericardial effusions are present in approximately 80% of cases. Motor development is usually delayed due to hypotonia. Most patients have a mild speech delay, and a small percentage have learning difficulties or intellectual disability. |
| Miscellaneous | May contribute to the regulation of sleep duration. An intronic variant of this gene may account for about 5% of the variation of sleep duration between individuals (Ref.4). Sleep duration is influenced both by environmental and genetic factors, with an estimated heritability of about 40%. Numerous genes are expected to contribute to the regulation of sleep duration. |
| Sequence similarities | Belongs to the ABC transporter superfamily. ABCC family. Conjugate transporter (TC 3.A.1.208) subfamily. [View classification] Contains 2 ABC transmembrane type-1 domains. Contains 2 ABC transporter domains. |

Alternative products
| This entry describes 2 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform SUR2A (identifier: O60706-1) This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Isoform SUR2B (identifier: O60706-2) The sequence of this isoform differs from the canonical sequence as follows: 1508-1549: SSIMDAGLVL...LFSTLVMTNK → HTILTADLVI...VFASFVRADM |
