Protein attributes

Sequence length	2171 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	May function as regulatory subunit of ATP-sensitive potassium channels (KATP) and form KATP channels with a member of the ATP-sensitive inward rectifier potassium channel family By similarity. May also have channel activity by itself (in vitro). May protect the heart during hypoxia. May protect against heart failure under conditions of tachycardic stress. Ref.1 Ref.4 Ref.5
Subcellular location	Membrane; Multi-pass membrane protein Probable.
Tissue specificity	Highly expressed in adult heart. Detected at lower levels in head and abdomen. Ref.4
Developmental stage	Detected in embryonic myocardial cells and in the developing heart tube. Detected in embryonic dorsal vessels and tracheal system. Ref.1 Ref.4
Miscellaneous	Drosophila is predominantly active around dawn and dusk, and has large sleep periods during the day and during night. Knockdown of Sur reduces sleep duration during the first half of the night, but has little effect on sleep during the day (Ref.5).
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.
Sequence caution	The sequence AAF06736.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.
