== Function ==
[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>
