[https://www.uniprot.org/uniprot/AKT1_ARATH AKT1_ARATH] Highly selective inward-rectifying potassium channel that mediate potassium uptake by plant roots in response to low K(+) conditions, by a calcium-, CBL-, and CIPK-dependent pathway. Positively regulated by phosphorylation by CIPK23. Negatively regulated by a kinase-independent regulatory mechanism involving a competing direct binding of CBL10. Involved in the stomatal regulation by monitoring the turgor pressure in guard cells. Assuming opened or closed conformations in response to the voltage difference across the membrane, the channel is activated by hyperpolarization. May interact with the cytoskeleton or with regulatory proteins.<ref>PMID:12678562</ref> <ref>PMID:16814720</ref> <ref>PMID:16895985</ref> <ref>PMID:17898163</ref> <ref>PMID:9572739</ref> | [https://www.uniprot.org/uniprot/AKT1_ARATH AKT1_ARATH] Highly selective inward-rectifying potassium channel that mediate potassium uptake by plant roots in response to low K(+) conditions, by a calcium-, CBL-, and CIPK-dependent pathway.
