A mitochondrial protein, able to specifically bind two double-stranded homologous sequences of sea-urchin mitochondrial DNA, has been partially purified from Paracentrotus lividus eggs. This protein, present at a low concentration, is a polypeptide of 40 kDa. One of the binding sequences, located in the main non-coding region, contains the replication origin of the mitochondrial DNA H-strand. By a combination of band-shift, DNase footprinting, and modification interference analyses with homologous and heterologous probes we identified YCYYATCAN(A/T)RC as the minimum sequence required for the binding. The protein also shows a single-stranded DNA-binding activity, as it is able to specifically interact with one of the strands of the binding sites. These features are consistent with a function of the protein in the modulation of sea-urchin mitochondrial DNA replication during the development stages.
