Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the translocation of calcium from the cytosol to the sarcoplasmic reticulum lumen. Involved in autophagy in response to starvation. Upon interaction with VMP1 and activation, controls ER-isolation membrane contacts for autophagosome formation. Also modulates ER contacts with lipid droplets, mitochondria and endosomes.

By similarity

Involved in the regulation of the contraction/relaxation cycle. Acts as a regulator of TNFSF11-mediated Ca2+ signaling pathways via its interaction with TMEM64 which is critical for the TNFSF11-induced CREB1 activation and mitochondrial ROS generation necessary for proper osteoclast generation. Association between TMEM64 and SERCA2 in the ER leads to cytosolic Ca2+ spiking for activation of NFATC1 and production of mitochondrial ROS, thereby triggering Ca2+ signaling cascades that promote osteoclast differentiation and activation.

Has different conformational states with differential Ca2+ affinity. The E1 conformational state (active form) shows high Ca2+ affinity, while the E2 state exhibits low Ca2+ affinity. Reversibly inhibited by phospholamban (PLN) at low calcium concentrations. Inhibited by sarcolipin (SLN) and myoregulin (MRLN). The inhibition is blocked by VMP1 (By similarity). Enhanced by DWORF; DWORF increases activity by displacing sarcolipin (SLN), phospholamban (PLN) and myoregulin (MRLN) (By similarity). Stabilizes SERCA2 in its E2 state (By similarity).By similarity

Ca2+ and ATP binding cause major rearrangements of the cytoplasmic and transmembrane domains. According to the E1-E2 model, Ca2+ binding to the cytosolic domain of the pump in the high-affinity E1 conformation is followed by the ATP-dependent phosphorylation of the active site Asp, giving rise to E1P. A conformational change of the phosphoenzyme gives rise to the low-affinity E2P state that exposes the Ca2+ ions to the lumenal side and promotes Ca2+ release. Dephosphorylation of the active site Asp mediates the subsequent return to the E1 conformation.By similarity
PLN and SLN both have a single transmembrane helix; both occupy a similar binding site that is situated between the ATP2A2 transmembrane helices.By similarity

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1. The algorithm is described in the ISO 3309 standard. </p> <p class="publication">Press W.H., Flannery B.P., Teukolsky S.A. and Vetterling W.T.<br /> <strong>Cyclic redundancy and other checksums</strong><br /> <a href="http://www.nrbook.com/b/bookcpdf.php">Numerical recipes in C 2nd ed., pp896-902, Cambridge University Press (1993)</a>)</p> Checksum:iCEE18D1A1ADA738F
