malfunction | a Mu transposon insertion in the Zea mays (maize) gene encoding a chloroplast dimerization co-factor of hepatocyte nuclear factor 1 (DCoH)/pterin-4a-carbinolamine dehydratases (PCD)-like protein is the causative mutation in a seedling-lethal, Rubisco-deficient mutant named Rubisco accumulation factor 2 (raf2-1). In raf2 mutants newly synthesized Rubisco large subunit accumulates in a high-molecular weight complex, the formation of which requires a specific chaperonin 60-kDa isoform. raf2 Mutant phenotype, overview | Zea mays |
physiological function | the maize gene Rubisco accumulation factor 2 (raf2) is required for Rubisco biogenesis. RAF2 is conserved among photosynthetic eukaryotes and is related to a mitochondrial protein: dimerization co-factor of hepatocyte nuclear factor 1 (DCoH)/pterin-4a-carbinolamine dehydratases (PCD)-like protein. The pterin-4a-carbinolamine dehydratases (PCD)-like protein RAF2 lacks PCD activity acquires a chloroplast-specific domain. Effect of RAF2 on the accumulation of rbcL and rbcs transcripts is investigated by gel blot analysis of total seedling leaf RNA from wild-type and raf2 mutants | Zea mays |
