CC -!- FUNCTION: Catalyzes the hydrolysis of ATP coupled with the transport of
CC calcium. {ECO:0000256|RuleBase:RU361146}.
CC -!- FUNCTION: Involved in the regulation of the contraction/relaxation
CC cycle. Acts as a regulator of TNFSF11-mediated Ca(2+) signaling
CC pathways via its interaction with TMEM64 which is critical for the
CC TNFSF11-induced CREB1 activation and mitochondrial ROS generation
CC necessary for proper osteoclast generation. Association between TMEM64
CC and SERCA2 in the ER leads to cytosolic Ca(2+) spiking for activation
CC of NFATC1 and production of mitochondrial ROS, thereby triggering
CC Ca(2+) signaling cascades that promote osteoclast differentiation and
CC activation. {ECO:0000256|ARBA:ARBA00045414}.
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. In
CC coordination with FLVCR2 mediates heme-stimulated switching from
CC mitochondrial ATP synthesis to thermogenesis.
CC {ECO:0000256|ARBA:ARBA00045861}.
CC -!- CATALYTIC ACTIVITY:

CC -!- SIMILARITY: Belongs to the cation transport ATPase (P-type) (TC 3.A.3)
CC family. Type IIA subfamily. {ECO:0000256|ARBA:ARBA00005675,
CC ECO:0000256|RuleBase:RU361146}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|RuleBase:RU361146}.
