1.A.1.5.24
Cyclic nucleotide-gated Na+ channel of 764 aas and 6 putative TMSs, CNGC20. Induced in shoots in response to salt (NaCl) stress (Kugler et al. 2009). CNGC20 self-associates, forms heteromeric complexes with CNGC19, and is phosphorylated and stabilized by BOTRYTIS INDUCED KINASE1 (BIK1). Tight control of the CNGC20 Ca2+ ion channel is important for regulating immunity (Zhao et al. 2021). Spermidine may play a role in salt stress in rice (Saha et al. 2020).
