Protein
50S ribosomal protein L21, mitochondrial
Organism
Arabidopsis thaliana
Function
This protein binds to 23S ribosomal RNA in the presence of protein L20 (By similarity). Required for karyogamy during female gametophyte development, when the two polar nuclei fuse to form the diploid central cell nucleus, and during double fertilization of the egg cell and the central cell (PubMed:16698901).
Similarity
Belongs to the bacterial ribosomal protein bL21 family.
