CBP7 codes for a co-factor required in conjunction with a mitochondrial maturase for splicing of its cognate intervening sequence.

The EMBO journal - 1 Sept 1990

Muroff I, Tzagoloff A

Abstract excerpt

Maturases are required for the processing of their cognate intervening sequences in the mitochondrial cytochrome beta pre-mRNA. In this paper we characterize a nuclear gene, CBP7, already known to be required for the translation of the cytochrome b transcript; we present further evidence that it is also required as a co-factor in conjunction with the maturases for the efficient processing of their intervening...
