Synonyms
  1. TAR RNA-binding protein 1
  2. TAR RNA-binding protein of 185 kDa
  3. TRP-185
Gene Name TARBP1
Protein Type Enzyme
Biological Properties
General Function Involved in binding
Specific 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
