| Primary Identifier | IPR040587 | Type | Domain |
| Short Name | XRN1_DBM |
| description | This domain is found in the 5'-3' exonuclease (XRN1) present in Drosophila melanogaster. XRN1 degrades deadenylated mRNA that has recently been decapped by decapping enzyme 2 (DCP2). DCP2 associates with decapping activators DCP1 and EDC4. The direct interaction between DCP1 and XRN1 couples mRNA decapping to 5' exonucleolytic degradation. This domain is responsible for binding to DCP1. In particular, the helical C-terminal region of the domain contributes to the binding affinity and the specificity of the interaction []. |
