BAIT

MRS1

PET157, YIR021W
Splicing protein; required for splicing of two mitochondrial group I introns (BI3 in COB and AI5beta in COX1); forms a splicing complex, containing four subunits of Mrs1p and two subunits of the BI3-encoded maturase, that binds to the BI3 RNA; MRS1 has a paralog, CCE1, that arose from the whole genome duplication

BI3

cytochrome b mRNA maturase bI3, L000004936, L000000176, Q0115
Mitochondrial mRNA maturase; forms a complex with Mrs1p to mediate splicing of the bI3 intron of the COB gene; encoded by both exon and intron sequences of partially processed COB mRNA

Kinetic and thermodynamic framework for assembly of the six-component bI3 group I intron ribonucleoprotein catalyst.

Bassi GS, Weeks KM

The yeast mitochondrial bI3 group I intron RNA splices in vitro as a six-component ribonucleoprotein complex with the bI3 maturase and Mrs1 proteins. We report a comprehensive framework for assembly of the catalytically active bI3 ribonucleoprotein. (1) In the absence of Mg(2+), two Mrs1 dimers bind independently to the bI3 RNA. The ratio of dissociation to association rate constants, k(off)/k(on), ... [more]

Synthetic Rescue

A genetic interaction is inferred when mutations or deletions of one gene rescues the lethality or growth defect of a strain mutated or deleted for another gene.
