Protein Structure
UniProt Annotation
Function This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the transport of calcium. Transports calcium ions from the cytosol into the sarcoplasmic/endoplasmic reticulum lumen. Contributes to calcium sequestration involved in muscular excitation/contraction. {ECO:0000269PubMed:11956212, ECO:0000269PubMed:15028735}.
Subcellular Localization Nucleus membrane {ECO:0000269PubMed:15028735}; Multi-pass membrane protein {ECO:0000269PubMed:15028735}. Endoplasmic reticulum membrane {ECO:0000269PubMed:15028735}; Multi-pass membrane protein {ECO:0000269PubMed:15028735}. Sarcoplasmic reticulum membrane {ECO:0000269PubMed:15028735}; Multi-pass membrane protein {ECO:0000269PubMed:15028735}.
Disease Associations
Tissue Specificity Found in most tissues. Most abundant in thymus, trachea, salivary gland, spleen, bone marrow, lymph node, peripheral leukocytes, pancreas and colon. Also detected in fetal tissues. Expressed in cell lineages of hematopoietic, epithelial, or embryonic origin and also expressed in several cancer cell lines. {ECO:0000269PubMed:11956212, ECO:0000269PubMed:15028735}.
