CBL3

Gene
CBL3
Protein
Calcineurin B-like protein 3
Organism
Arabidopsis thaliana
Length
226 amino acids
Function
Acts as a calcium sensor. CBL proteins interact with CIPK serine-threonine protein kinases. Binds calcium ions. Binding of a CBL protein to the regulatory NAF domain of a CIPK protein lead to the activation of the kinase in a calcium-dependent manner. Mediates the activation of AKT1 by CIPK proteins (CIPK6, CIPK16, and CIPK23) in response to low potassium conditions and in the context of stomatal movement. Negatively regulates the enzyme activity of MTN1 in the presence of calcium.
Similarity
Belongs to the calcineurin regulatory subunit family.
