Descriptions
Calcium-transporting ATPases (ACAs) catalyze the hydrolysis of ATP coupled with the translocation of calcium. The N-terminal region interacts with calmodulin in the same protein and it contains an autoinhibitory region at N-terminus.

Target domain |
414-786 (ATPase domain) |
Relief mechanism |
Partner binding |
