Anti-TRBP2

0.5 mg/ml with 0.1 mg/ml BSA (US sourced), 0.05% sodium azide. TRBP2 (TAR (HIV-1) RNA binding protein 2) , along with Dicer and Argonaute-2, is part of the RISC (RNA induced silencing complex). As part of the RISC, TRBP2 is important in viral defense. Dicer cleaves dsRNA into siRNA. Through TRBP2-Dicer interaction, the siRNA template is loaded onto Argonaute-2, which cleaves encountered viral mRNA strands complementary to the loaded siRNA base-pair sequence. Protein function: Required for formation of the RNA induced silencing complex (RISC). Component of the RISC loading complex (RLC), also known as the micro-RNA (miRNA) loading complex (miRLC), which is composed of DICER1, AGO2 and TARBP2. Within the RLC/miRLC, DICER1 and TARBP2 are required to process precursor miRNAs (pre-miRNAs) to mature miRNAs and then load them onto AGO2. AGO2 bound to the mature miRNA constitutes the minimal RISC and may subsequently dissociate from DICER1 and TARBP2. May also play a role in the production of short interfering RNAs (siRNAs) from double-stranded RNA (dsRNA) by DICER1. Binds to the HIV-1 TAR RNA which is located in the long terminal repeat (LTR) of HIV-1, and stimulates translation of TAR-containing RNAs. This is achieved in part at least by binding to and inhibiting EIF2AK2/PKR, thereby reducing phosphorylation and inhibition of EIF2S1/eIF-2-alpha. May also promote translation of TAR-containing RNAs independently of EIF2AK2/PKR. [The UniProt Consortium]
