Soybean cyclophilin GmCYP1 interacts with an isoflavonoid regulator GmMYB176.

ABSTRACT: Cyclophilins (CYPs) belong to the immunophilin superfamily with peptidyl-prolyl cis-trans isomerase (PPIase) activity. They catalyze the interconversion of the cis- and trans-rotamers of the peptidyl-prolyl amide bond of peptides. A yeast-two-hybrid screening using the isoflavonoid regulator GmMYB176 as bait identified GmCYP1 as one of the interacting proteins in soybean embryos. GmCYP1 localizes both in the nucleus and cytoplasm, and interacts in planta with GmMYB176, in the nucleus, and with SGF14l (a soybean 14-3-3 protein) in the nucleus and the cytoplasm. GmCYP1 contains a single cyclophilin-like domain and displays a high sequence identity with other plant CYPs that are known to have stress-specific function. Tissue-specific expression of GmCYP1 revealed higher expression in developi
