DBR1 is an RNA lariat debranching enzyme that hydrolyzes 2-5 prime branched phosphodiester bonds. The encoded protein specifically targets the bonds at the branch point of excised lariat intron RNA, converting them to linear molecules that are then degraded. This protein may also be involved in retroviral replication. Recombinant protein corresponding to aa228-544 from human DBR1, fused to His-tag at N-terminal expressed in E. coli.
