TAR RNA Binding Protein 2 (TARBP2) is a component of the RISC loading complex which takes part in the production of short interfering RNAs (siRNAs) from double-stranded RNA (dsRNA) by DICER1. TARBP2, which is also known as the micro-RNA (miRNA) loading complex (miRLC), contains three DRBM (double-stranded RNA-binding) domains. TARBP2 binds to the HIV-1 TAR RNA and stimulates translation of TAR-containing RNAs.
TARBP2 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 345 amino acids (1-345 a.a) and having a molecular mass of 36.9kDa. TARBP2 is purified by proprietary chromatographic techniques.
UniProt Protein Function: | TRBP: the HIV-1 TAR RNA binding protein (TRBP) is a double strand RNA binding protein (dsRBP) that is required for the recruitment of Ago2 to the small interfering RNA (siRNA) bound by Dicer. TRBP increases HIV-1 expression and replication by inhibiting the interferon-induced protein kinase PKR and by increasing translation of viral mRNA. Dicer, Ago2, and TRBP are the main components of the RNA-induced silencing complex (RISC). |

NCBI Summary: | HIV-1, the causative agent of acquired immunodeficiency syndrome (AIDS), 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. The protein encoded by this gene 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 splicing results in multiple transcript variants encoding different isoforms. This gene also has a pseudogene. [provided by RefSeq, Jul 2008] |
