This presumed domain is found in TEP1 and Ro60 proteins, that are RNA-binding components of Telomerase, Ro and Vault RNPs. This domain has been named TROVE, (after Telomerase, Ro and Vault). This domain is probably RNA-binding.
The TROVE (Telomerase, Ro and Vault) domain is a module of ~300-500 residues that is found in TEP1 and Ro60 the protein components of three ribonucleoprotein particles. It is also found in bacterial ribonucleoproteins suggesting an ancient origin of these ribonucleoproteins. It can be found associated with other domains, such as the VWFA domain, the TEP1 N-terminal domain, the NACHT-NTPase domain, and WD-40 repeats. This domain may be involved in binding the RNA components of the three RNPs, which are telomerase RNA, Y RNA and vault RNA [PUBMED:14563212].
