CELE_C55B7.8, Ce-dbr1, C55B7.8

dbr-1 encodes a homolog of the RNA lariat-debranching enzyme; DBR-1 is predicted to function in RNA processing by hydrolyzing the 2'-5' phosphodiester bond at the branchpoint of excised lariat intron RNA, thus converting the introns into linear molecules that can subsequently be degraded by exonucleases; in C. elegans, DBR-1 activity is required for embryonic and germline development, as well as for normal rates of postembryonic growth; overexpression of C. elegans DBR-1 in Saccharomyces cerevisiae can complement the RNA processing defects of a dbr1 null mutant strain, restoring debranching activity and intron degradation to near wild-type levels.
