Summary: This gene encodes one of the SERCA Ca(2+)-ATPases, which are intracellular pumps located in the sarcoplasmic or endoplasmic reticula of muscle cells. This enzyme catalyzes the hydrolysis of ATP coupled with the translocation of calcium from the cytosol to the sarcoplasmic reticulum lumen, and is involved in muscular excitation and contraction. Mutations in this gene cause some autosomal recessive forms of Brody disease, characterized by increasing impairment of muscular relaxation during exercise. Alternative splicing results in three transcript variants encoding different isoforms. [provided by RefSeq, Oct 2013]

Study demonstrated that (a) the distribution and the expression levels of total SERCA1 and SERCA2, the activity of SR Ca2+ ATPase, and the oligomerization of SERCA1 are similar in patients with myotonic dystrophy 1, myotonic dystrophy 2, hypothyroid myopathy and control subjects; and (b) SERCA1b is expressed in patients with myotonic dystrophy, mainly in myotonic dystrophy 2 muscles.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
