UniProtKB - P93280 (CCMB_ARATH)
Protein
Putative cytochrome c biogenesis ccmB-like mitochondrial protein
Gene
CCMB
Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Functioni
May be involved in the export of heme to the mitochondrion for the biogenesis of c-type cytochromes.
Caution
Was originally (PubMed:18299247) thought to belong to the ABC transporter family. Lacks the conserved ABC domain, which is one of the features of the ABC transporter family.1 Publication
