CC -!- FUNCTION: This magnesium-dependent enzyme catalyzes the hydrolysis of
CC ATP coupled with the translocation of calcium from the cytosol to the
CC sarcoplasmic reticulum lumen. Involved in autophagy in response to
CC starvation. Upon interaction with VMP1 and activation, controls ER-
CC isolation membrane contacts for autophagosome formation. Also modulates
CC ER contacts with lipid droplets, mitochondria and endosomes (By
CC similarity). {ECO:0000250|UniProtKB:P16615,
CC ECO:0000269|PubMed:22355118, ECO:0000269|PubMed:22971924}.
CC -!- FUNCTION: [Isoform 2]: Involved in the regulation of the
CC contraction/relaxation cycle (PubMed:23395171). Acts as a regulator of
CC TNFSF11-mediated Ca(2+) signaling pathways via its interaction with
CC TMEM64 which is critical for the TNFSF11-induced CREB1 activation and
CC mitochondrial ROS generation necessary for proper osteoclast generation
CC (PubMed:23395171). Association between TMEM64 and SERCA2 in the ER
CC leads to cytosolic Ca(2+) spiking for activation of NFATC1 and
CC production of mitochondrial ROS, thereby triggering Ca(2+) signaling
CC cascades that promote osteoclast differentiation and activation
CC (PubMed:23395171). {ECO:0000269|PubMed:23395171}.

CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:18106;
CC Evidence={ECO:0000269|PubMed:28890335};
CC -!- ACTIVITY REGULATION: Has different conformational states with
CC differential Ca2+ affinity. The E1 conformational state (active form)
CC shows high Ca(2+) affinity, while the E2 state exhibits low Ca(2+)
CC affinity. Reversibly inhibited by phospholamban (PLN) at low calcium
CC concentrations (PubMed:22971924). Inhibited by sarcolipin (SLN) and
CC myoregulin (MRLN). The inhibition is blocked by VMP1 (By similarity).
CC Enhanced by DWORF; DWORF increases activity by displacing sarcolipin
CC (SLN), phospholamban (PLN) and myoregulin (MRLN) (By similarity).
CC Stabilizes SERCA2 in its E2 state (By similarity).

CC -!- SUBUNIT: Interacts with sarcolipin (SLN); the interaction inhibits
CC ATP2A2 Ca(2+) affinity (By similarity). Interacts with phospholamban

CC -!- TISSUE SPECIFICITY: Isoform 2 is highly expressed in heart and slow
CC twitch skeletal muscle. Isoform 2 is widely expressed.
CC -!- INDUCTION: Highly up-regulated during osteoclast differentiation.
CC {ECO:0000269|PubMed:23395171}.
CC -!- DOMAIN: Ca(2+) and ATP binding cause major rearrangements of the
CC cytoplasmic and transmembrane domains. According to the E1-E2 model,
CC Ca(2+) binding to the cytosolic domain of the pump in the high-affinity
CC E1 conformation is followed by the ATP-dependent phosphorylation of the
CC active site Asp, giving rise to E1P. A conformational change of the
CC phosphoenzyme gives rise to the low-affinity E2P state that exposes the
CC Ca(2+) ions to the lumenal side and promotes Ca(2+) release.
CC Dephosphorylation of the active site Asp mediates the subsequent return
CC to the E1 conformation. {ECO:0000250|UniProtKB:P04191}.
CC -!- DOMAIN: PLN and SLN both have a single transmembrane helix; both occupy
CC a similar binding site that is situated between the ATP2A2
CC transmembrane helices. {ECO:0000250|UniProtKB:P04191}.
CC -!- PTM: Nitrated under oxidative stress. Nitration on the two tyrosine
CC residues inhibits catalytic activity. {ECO:0000250|UniProtKB:P16615}.
CC -!- PTM: Serotonylated on Gln residues by TGM2 in response to hypoxia,
CC leading to its inactivation. {ECO:0000269|PubMed:32116663}.
CC -!- DISRUPTION PHENOTYPE: Sarcoplasmic reticulum collapse and volume
CC reduction. Although dimensions of cardiomyocyte are not affected, total
CC surface area is significantly increased, resulting in increased T-
CC tubule density. {ECO:0000269|PubMed:22355118}.
CC -!- SIMILARITY: Belongs to the cation transport ATPase (P-type) (TC 3.A.3)
CC family. Type IIA subfamily. {ECO:0000305}.
