[[ | [[https://www.uniprot.org/uniprot/CNBL4_ARATH CNBL4_ARATH]] Acts as a calcium sensor involved in the regulatory pathway for the control of intracellular Na(+) and K(+) homeostasis and salt tolerance. Operates in synergy with CIPK24/SOS2 to activate the plasma membrane Na(+)/H(+) antiporter SOS1. May function as positive regulator of salt stress responses. 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.<ref>PMID:11006339</ref> <ref>PMID:10725350</ref> <ref>PMID:12034882</ref> [[https://www.uniprot.org/uniprot/CIPKO_ARATH CIPKO_ARATH]] Involved in the regulatory pathway for the control of intracellular Na(+) and K(+) homeostasis and salt tolerance. Activates the vacuolar H(+)/Ca(2+) antiporter CAX1 and operates in synergy with CBL4/SOS3 to activate the plasma membrane Na(+)/H(+) antiporter SOS1. CIPK serine-threonine protein kinases interact with CBL proteins. Binding of a CBL protein to the regulatory NAF domain of CIPK protein lead to the activation of the kinase in a calcium-dependent manner. Phosphorylates CBL1, CBL4 and CBL10.<ref>PMID:10725350</ref> <ref>PMID:12034882</ref> <ref>PMID:14583601</ref> <ref>PMID:22253446</ref> | ||
