RT "Conserved regulation of cardiac calcium uptake by peptides encoded in
RT small open reading frames.";
RL Science 341:1116-1120(2013).
CC -!- FUNCTION: Plays an essential role in the regulation of calcium
CC transport at the sarcoplasmic reticulum (SR), which is secondarily
CC required for regular muscle contraction. {ECO:0000269|PubMed:23970561}.
CC -!- SUBUNIT: Interacts with SERCA. {ECO:0000269|PubMed:23970561}.
CC -!- SUBCELLULAR LOCATION: Sarcoplasmic reticulum membrane
CC {ECO:0000269|PubMed:23970561}; Single-pass membrane protein
CC {ECO:0000269|PubMed:23970561}. Note=Colocalizes with SERCA at the
CC sarcoplasmic reticulum and the diad, a structure composed of a single
CC t-tubule paired with a terminal cisterna of the sarcoplasmic reticulum.
CC {ECO:0000269|PubMed:23970561}.
CC -!- TISSUE SPECIFICITY: Strongly expressed in embryonic and larval somatic
CC muscles and postembryonic heart. {ECO:0000269|PubMed:23970561}.
CC -!- DISRUPTION PHENOTYPE: SclA and SclB double mutants show arrhythmic
CC cardiac contractions and correspondingly, cardiac cells show irregular
CC action potentials (APs), involving 'double' and occasionally failed
CC APs. Calcium transients in these mutants show higher amplitudes and
CC steeper decay than those in wild type flies.
CC {ECO:0000269|PubMed:23970561}.
CC -!- MISCELLANEOUS: This protein is produced by a bicistronic gene which
CC also produces the SclA protein from a non-overlapping reading frame.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAL48870.1; Type=Erroneous translation; Note=Wrong choice of frame.; Evidence={ECO:0000305};
