Abstract

This entry includes CEP1 from Arabidopsis thaliana (At1g47485, Q8L8Y3 ) and its homologues from plants. They may serve as negative regulators that mediate environmental influences on plant development [ 1 ]. CEP1 is secreted as a 15-amino acid peptide originating from a C-terminal conserved domain (the CEP domain) through posttranslational proline hydroxylation and proteolytic processing [ 2 ].
