THUMP--a predicted RNA-binding domain shared by 4-thiouridine, pseudouridine synthases and RNA methylases

Trends Biochem Sci. 2001 Apr;26(4):215-7. doi: 10.1016/s0968-0004(01)01826-6.

Abstract

Sequence profile searches were used to identify an ancient domain in ThiI-like thiouridine synthases, conserved RNA methylases, archaeal pseudouridine synthases and several uncharacterized proteins. We predict that this domain is an RNA-binding domain that adopts an alpha/beta fold similar to that found in the C-terminal domain of translation initiation factor 3 and ribosomal protein S8.
