DBR1 cDNA ORF clone, Homo sapiens(human)
Gene Symbol | DBR1 |
Entrez Gene ID | 51163 |
Full Name | debranching RNA lariats 1 |
General protein information |
|
Gene Type | protein-coding |
Organism | Homo sapiens(human) |
Genome | |
Summary | The protein encoded by this gene 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. [provided by RefSeq, Nov 2011]. |
