A0A1P8BBZ1_ARATH | function | Acts as a calcium sensor. CBL proteins interact with CIPK serine-threonine protein kinases. 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. |
CNBL9_ARATH | function | Acts as a calcium sensor involved in abscisic acid (ABA) signaling and stress-induced ABA biosynthesis pathways. Contributes to the regulation of early stress-related CBF/DREB transcription factors. CBL proteins interact with CIPK serine-threonine protein kinases. 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. May function as a negative regulator of stress and ABA responses. 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. Involved in the calcium-dependent regulation by CIPK26 of reactive oxygen species production by the NADPH oxidase RBOHF. The CBL9/CIPK3 complex acts in the regulation of abscisic acid response in seed germination. |
A0A1P8BBZ1_ARATH CNBL9_ARATH | similarity | Belongs to the calcineurin regulatory subunit family. |
CNBL9_ARATH | subcellular location | Plasma membrane localization abolished by 2-bromopalmitate (2-BP) treatment. |
CNBL9_ARATH | tissue specificity | Ubiquitous. Colocalized with CIPK23 in root tips and vascular bundles in the stem and the leaf, as well as in guard cells and root hairs. |
