Calcium binding protein P22, also known as CHP, is a human gene.[1]

The protein encoded by this gene is a phosphoprotein that binds to the sodium-hydrogen exchangers (NHEs). This protein serves as an essential cofactor which supports the physiological activity of NHE family members. It has protein sequence similarity to calcineurin B and it is also known to be an endogenous inhibitor of calcineurin activity.[1]

Interactions[edit]

CHP (gene) has been shown to interact with Sodium-hydrogen antiporter 1[2][3][4] and Sodium-hydrogen antiporter 3.[2]
