TRBP1 Antibody

TRBP1 Antibody

Catalog# : 4011

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 1alpha (EF-1alpha), 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.
Additional Names : TRBP1 (IN), TAR RNA binding protein 1, TARBP1, TRP-185, TRP-1

Hi all,

TRBP1 has been isolated based on the ability of the protein that it encodes to bind RNA. It activates the basal of the HIV-1 LTR in human and murine cells. Thanks a lot.......
