Lariat debranching enzyme is a protein that in humans is encoded by the DBR1 gene.[5][6]

The RNA lariat debranching enzyme, or DBR1, specifically hydrolyzes 2-prime-to-5-prime branched phosphodiester bonds at the branch point of excised lariat intron RNA and converts them into linear molecules.[supplied by OMIM][6]
