|Application ||WB, E|
|Other Accession||NP_005637, 110825988|
|Calculated MW||181675 Da|
|Application Notes||TRBP1 antibody can be used for detection of TRBP1 by Western blot at 1 - 2 µg/mL.|
|Other Names||TRBP1 Antibody: TRM3, TRP185, TRP-185, TRM3, Probable methyltransferase TARBP1, TAR RNA-binding protein 1, TAR (HIV-1) RNA binding protein 1|
|Reconstitution & Storage||TRBP1 antibody can be stored at 4℃ for three months and -20℃, stable for up to one year. As with all antibodies care should be taken to avoid repeated freeze thaw cycles. Antibodies should not be exposed to prolonged high temperatures.|
|Precautions||TRBP1 Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|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.|

TRBP1 Antibody: The human trans-activation response (TAR) RNA binding protein 1 (TRBP1) was initially identified as a protein that binds to the HIV-1 TAR RNA and activates the long terminal repeat (LTR) expression in the absence and presence of the viral trans-activator Tat. This binding is enhanced by the presence of co-factors such as elongation factor 1α (EF-1α), polypyrimidine tract-binding protein (PTB), and the chaperonin-like protein stimulator of TAR RNA-binding proteins (SRB). TRBP1 may act to disengage RNA polymerase II from TAR during transcriptional elongation if the RNA polymerase stalls at the TAR during transcriptional elongation.
