These results establish that PKR regulation through stress-induced TRBP phosphorylation is an important mechanism ensuring cellular recovery and preventing apoptosis due to sustained PKR activation.
A statistically significant association with the risk of AD was observed with the CT genotype for rs784567 on the TARBP2 gene. on controlling for age and sex, we found that for the TARBP2-RNASEN association with AD the age variation was a risk factor for AD risk (P<0.001; OR=1.104; 95% CI, 1.059-1.151).
TRBP is a novel transcriptional coactivator of the Notch signaling pathway, playing an important role in neural stem cell regulation during mammalian brain development
TRBP is required for normal antiviral responses to Cardiovirus infection.
Experimental and computational techniques were employed to examine the hypothesis that TRBP-double-stranded RNA-binding domain (dsRBD) 2 binding by a 20-mer dsRNA is coupled with RNA bending, results suggest that this particular dsRBD-dsRNA interaction produces little to no change in the A-form geometry of dsRNA in solution
We propose that the S6K2/TRBP node controls miRNA biogenesis in HDLECs and provides a molecular link between the mTOR pathway and the miRNA biogenesis machinery.
TARBP2 silencing inhibits in vitro invasion and migration of NCIH1299 nonsmall cell lung cancer cell via the JNK/STAT3/AKT pathway. TARBP2 silencing does not significantly affect cell growth.
TARBP2 has roles in tumor development and progression [review]
SUMOylation of TARBP2 is required for regulating siRNA efficiency.
HIV-1 Rev-response element RNA acts as an RNA silencing suppressor by competing with TRBP-bound siRNAs.
the role of TRBP and unveils negative feedback regulation of PKR through TRBP phosphorylation.
Results show the crystal structure of the interface between microRNA biogenesis proteins Dicer and TRBP. Mutations in this interface prevent recruitment of TRBP to Dicer.
RPL5 binds to the TRBP2 and Ago2 subunits of the RISC and mediates the binding to c-Myc 3'UTR.
TARBP2 expression is upregulated in late-stage breast cancer and triple-negative breast cancer and may have a role in poorer disease-free survival and overall survival
identified TARBP2, a double-stranded RNA-binding protein implicated in microRNA processing, as the trans factor that binds the sRSE family and similar structural elements--collectively termed TARBP2-binding structural elements (TBSEs)--in transcripts
Tarbp2 binding to TRPC4 promotes changes of cytosolic Ca(2+) and, thereby, leads to a dynamic regulation of Dicer activity, essentially at low endogenous Dicer concentrations.
mRNA expression of TARBP2, but not DICER or DROSHA, is a strong molecular predictor to discriminate between adrenocortical adenomas and carcinomas
in vitro binding patterns of human TRBP and PACT to siRNA
The results show that PACT and TRBP have distinct effects on Dicer-mediated dsRNA processing.
No frameshift mutations in TARBP2 were identified in a study of 4 cases of upper urinary tract urothelial carcinoma with high microsatellite instability status.
TARBP2, but not PRKRA, functions in miRNA biogenesis of a subclass of miRNAs, and suggesting that functional redundancy between TARBP2 and PRKRA does not involve miRNA biogenesis.
study demonstrated that Trbp participates in the regulation of muscle differentiation and regeneration
These data indicate that the association between PKR and TRBP integrates metabolism with translational control and inflammatory signaling and plays important roles in metabolic homeostasis and disease.
Trbp (Tarbp2), an RNA-binding protein, is required for normal heart function.
The mammalian Dicer-partner TRBP, a Loqs-PB homolog, tunes where Dicer cleaves pre-miR-132. [TRBP]
TRBP controls PACT activation of PKR, an activity that is reversed by stress.
Binding of Dicer to TRBP is critical for RNAi function.
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.
