InterPro domain: IPR044233

This entry represents a group of predicted plant peptidyl-prolyl cis-trans isomerases, including AtCYP23 from Arabidopsis and OsCYP23 from rice [ 1 , 2 ]. OsCYP23 is ER-located and may be associated with specific substrates for metabolic regulation related to sodium or chloride ions [ 3 ].
