Description
Description: This gene shares similarity with the mouse Dhm1 and the yeast dhp1 gene. The yeast gene is involved in homologous recombination and RNA metabolism, such as RNA synthesis and RNA trafficking. Complementation studies show that Dhm1 has a similar function in mouse as dhp1. The function of the human gene has not yet been determined. Transcript variants encoding different isoforms have been noted for this gene; however, their full-length nature is not known.
Function: Possesses 5'-> 3' exoribonuclease activity (By similarity). May promote the termination of transcription by RNA polymerase II. During transcription termination, cleavage at the polyadenylation site liberates a 5' fragment which is subsequently processed to form the mature mRNA and a 3' fragment which remains attached to the elongating polymerase. The processive degradation of this 3' fragment by this protein may promote termination of transcription. Binds to RNA polymerase II (RNAp II) transcription termination R-loops formed by G-rich pause sites (PubMed:21700224).
Subunit Structure: Interacts with POLR2A and SMN1/SMN2 (PubMed:26700805). Interacts with CDKN2AIP and NKRF (PubMed:24462208). Interacts with CDKN2AIPNL; the interaction is direct (PubMed:26779609). Interacts with TRIM71 (via NHL repeats) in an RNA-dependent manner (PubMed:23125361).
Similarity: Belongs to the 5'-3' exonuclease family. XRN2/RAT1 subfamily
