THADA/TRM732, DUF2428 This conserved domain is found in Thyroid adenoma-associated proteins (THADA) and the yeast homolog, TRM732. Trm732 forms a complex with the methyltransferase Trm7 to 2'- O-methylate tRNA residue 32 (Nm32), being required for Trm7 methylation activity. In humans, mutations of the Trm7 homolog FTSJ1, which interacts with THADA, impair Nm32 modifications, associated with non-syndromic X-linked intellectual disability. It has been suggested that these proteins may play a role in additional biological processes not related to translation. This domain contains a RRSAGLP conserved motif that is required for tRNA modification activity (Funk HM et.al., Preprint from bioRxiv, 03 Jun 2021 DOI: 10.1101/2021.06.03.446962).
