Gene Ontology:

• GO:0009535  — located in — chloroplast thylakoid membrane
• GO:0003756  — enables — protein disulfide isomerase activity
• GO:0043621  — enables — protein self-association
• GO:0009658  — acts upstream of or within — chloroplast organization
• GO:0005515  — enables — protein binding
• GO:0009507  — located in — chloroplast

Germplasm Phenotype:

• CS68145  — Pale cotyledons and green true leaves in 14 day-old seedlings; however, upon precocious germination, seedlings of sco2 and wild-type are indistinguishable. Reduced survival rate upon exposure to an extended period of etiolation compared to wild-type.
• cyo1  — Albino cotyledons, abnormal chloroplast biogenesis. True leaves are not affected, chloroplast development during embryo biogenesis is not affected. Affected in photomorphogenesis after prolonged skotomorphogenesis (after 4 days in dark unable to undergo photomorphogenesis).
• sco2-1  — Albino cotyledons, abnormal chloroplast biogenesis. True leaves are not affected, chloroplast development during embryo biogenesis is not affected. Affected in photomorphogenesis after prolonged skotomorphogenesis (after 4 days in dark unable to undergo photomorphogenesis).
• sco2-2  — Albino cotyledons, abnormal chloroplast biogenesis. True leaves are not affected, chloroplast development during embryo biogenesis is not affected. Affected in photomorphogenesis after prolonged skotomorphogenesis (after 4 days in dark unable to undergo photomorphogenesis).
