This domain is found at the C-terminal end of DIS3-like exonuclease 2 from Schizosaccharomyces pombe (Dis32) and similar fungal proteins. Dis32, also known as Dis3l2, is a 3'-5'-exoribonuclease that specifically recognises RNAs polyuridylated at their 3' end and mediates their degradation. This domain shows three antiparallel beta -strands that show OB-fold characteristics [1].	Domain
