Protein Name: 5'-3' exoribonuclease

UniprotKB/SwissProt ID: D4A914 (D4A914)

Gene Name: Xrn2

Organism: Rattus norvegicus (Rat)

Function: Possesses 5'->3' exoribonuclease activity. May promote termination of transcription by RNA polymerase II Possesses 5'->3' exoribonuclease activity. 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
