| Description | This entry represents the C-terminal methyltransferase domain of TARBP1 and Trm3 [ ].Yeast tRNA (guanosine(18)-2'-O)-methyltransferase Trm3 catalyses the formation of 2'-O-methylguanosine at position 18 (Gm18) in various tRNAs []. Trm3 is similar to C-terminal domain of TAR (HIV-1) RNA binding protein 1 (TARBP1), a protein binding to TAR, which functions as a RNA regulatory signal by forming a stable stem-loop structure to which transactivator protein Tat binds. The role of TARBP1 is believed to be to disengage RNA polymerase II from TAR during transcriptional elongation [, ]. | Name | Trm3/ TARBP1, C-terminal |
| Short Name | Trm3/TARBP1_C | Type | Domain |
