| description | The calcium sensing receptor (CAS) from Arabidopsis is a thylakoid-localised phosphoprotein that possesses a single transmembrane domain that splits the protein into two halves: the N-terminal domain which binds Ca2 with low affinity and high capacity, and the C-terminal domain that contains a non-catalytic rhodanese homology domain and phosphorylation sites []. It modulates cytoplasmic Ca2 levels and it is required for proper stomatal regulation in response to elevated levels of external Ca2 []and it is also involved in de-etiolation []. This protein also plays a role in the STN7/STN8/TAP38 network of phosphorylation-mediated photoacclimation processes in Arabidopsis []. |
