NCBI Protein Information
protein disulfide isomerase
NCBI Summary
Encodes a zinc finger protein that is similar to a subgroup of DnaJ and is involved in cotyledon chloroplast biogenesis. Cyo1 is localized to the thylakoid membrane and has protein disulfide isomerase activity in vivo.Cyo1 is more highly expressed in light grown seedlings. Loss of function mutants have albino cotyledons and abnormal plastids.

UniProt Comments
Protein disulfide-isomerase involved in chloroplast development in cotyledons. Involved in the process of vesicle-derived thylakoid formation, probably at the level of the integration and folding of LHCB proteins at the initial location of integration. Acts only in germinating seeds after dormancy, during the transition from heterotrophic to autotrophic growth.
