Summary
CP12-1 encodes a small peptide found in the chloroplast stroma. It belongs to the CP12 gene family thought to be involved in the formation of a supramolecular complex with glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and phosphoribulokinase (PRK) embedded in the Calvin cycle.

GeneRIFs: Gene References Into Functions

What's a GeneRIF?
  1. Single cp12-1, cp12-2, and cp12-3 mutants do not develop a severe photosynthetic or growth phenotype. In contrast, reductions of both CP12-1 and CP12-2 transcripts lead to reductions in photosynthetic capacity and to slower growth and reduced seed yield. No clear phenotype for CP12-3 was evident.

  3. CP12 in oxygen phototrophs needs to be extended beyond light/dark regulation, and include protection of enzymes belonging to Calvine-Benson cycle from oxidative stress.

  4. All CP12 isoforms formed, in vitro, a supramolecular complex with GAPDH and PRK, with comparable inhibitory effects on both enzyme activities.

  5. CP12-1 and CP12-2 expression was detected in the sepals and the style of the flower, while CP12-3 was restricted to the stigma and anthers.
