The THUMP domain consists of about 110 amino acid residues. This domain is found in many tRNA modification enzymes classified into five types, namely 4-thiouridine synthetase, deaminase, methyltransferase, a partner protein of acetyltransferase and pseudouridine synthase [3]. The structure of ThiI reveals that the THUMP has a fold unlike that of previously characterised RNA-binding domains [2-3] and was first predicted to function by delivering a variety of RNA modification enzymes to their targets [1]. Studies performed in tRNA 4-thiouridine synthetase, tRNA methyltransferases and tRNA deaminase suggest that the THUMP domain captures the 3'-end of RNA but in some cases this is not applicable due to the modification patterns observed in tRNA [3]. Several THUMP-related proteins are also involved in other RNAs modifications, such as rRNA modification [3].	Domain
