Last Modified 2014-10-13 [Report errors or provide feedback]
Gene Symbol TARBP1
Protein Name TAR (HIV-1) RNA binding protein 1
Synonyms TRM3; TRP-185; TRP185;
Species Homo sapiens
Ensembl Protein ENSP00000040877
InnateDB Gene IDBG-107510 (TARBP1)
Protein Structure
UniProt Annotation
Function 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. {ECO:0000269PubMed:7638159, ECO:0000269PubMed:8626763, ECO:0000269PubMed:8846792}.
