Target

Full Name
TARBP2 Gene(Protein Coding) TARBP2, RISC Loading Complex RNA Binding Subunit
Introduction
HIV-1, the causative agent of acquired immunodeficiency syndrome, contains an RNA genome that produces a chromosomally integrated DNA during the replicative cycle. Activation of HIV-1 gene expression by the transactivator Tat is dependent on an RNA regulatory element (TAR) located downstream of the transcription initiation site. TARBP2 binds between the bulge and the loop of the HIV-1 TAR RNA regulatory element and activates HIV-1 gene expression in synergy with the viral Tat protein.

Alternative Names
TARBP2, RISC Loading Complex RNA Binding Subunit; TAR (HIV-1) RNA Binding Protein 2; TRBP; Trans-Activation Responsive RNA-Binding Protein; Trans-Activation-Responsive RNA-Binding Protein; RISC-Loading Complex Subunit TARBP2; TAR (HIV) RNA-Binding Protein TRBP1
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.
(Microbial infection) 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 (PubMed:2011739, PubMed:11438532, PubMed:12475984).
This is achieved in part at least by binding to and inhibiting EIF2AK2/PKR, thereby reducing phosphorylation and inhibition of EIF2S1/eIF-2-alpha (PubMed:11438532).
May also promote translation of TAR-containing RNAs independently of EIF2AK2/PKR (PubMed:12475984).
Mediates recruitment of FTSJ3 methyltransferase to HIV-1 RNA, leading to 2'-O-methylation of the viral genome, allowing HIV-1 to escape the innate immune system (PubMed:30626973).
