Plasma membrane calcium-transporting ATPase 1

Gene

Atp2b1

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the transport of calcium. Involved in bone homeostasis. Has a role in osteoclastogenesis where it regulates RANKL-induced calcium oscillation, a key step in the differentiation process. Also promotes survival of mature osteoclasts, probably by preventing toxic accumulation of intracellular calcium.UniRule annotation1 Publication

Catalytic activityi

ATP + H2O + Ca2+(Side 1) = ADP + phosphate + Ca2+(Side 2).UniRule annotation

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
