== Function ==
 +
[https://www.uniprot.org/uniprot/TARB1_HUMAN TARB1_HUMAN] Probable S-adenosyl-L-methionine-dependent methyltransferase which methylates RNA molecules such as tRNAs. In case of infection by HIV-1, it binds to the loop region of TAR RNA, a region also bound by RNA polymerase II. Binding of TARBP1 and RNA polymerase II to HIV-1 TAR RNA is mutually exclusive, suggesting that TARBP1 may function alone or in conjunction with HIV-1 Tat to disengage RNA polymerase II from HIV-1 TAR RNA. May act by methylating HIV-1 TAR RNA.<ref>PMID:7638159</ref> <ref>PMID:8626763</ref> <ref>PMID:8846792</ref>
