CATION TRANSPORTING ATPASE (PTHR24093) |
Descriptions
Calcium-transporting ATPases (ACAs) catalyze the hydrolysis of ATP coupled with the translocation of calcium. The N-terminal region of ACA8 is responsible for pump autoinhibition and the binding of calmodulin to the N-terminal region results in pump activation. The N-terminal truncated ATPase (△74-aca8) has high basal activity. In other words, the truncation of the N terminus releases autoinhibition of pump activity.
