Background: Dicer is a member of the RNase III family that specifically cleaves double-stranded RNAs to generate microRNAs (miRNAs) (1). After long primary transcript pri-miRNAs are processed to stem-looped pre-miRNAs by Drosha (2), pre-miRNAs are transported to the cytoplasm and further processed by Dicer to produce 22-nucleotide mature miRNAs (3). The mature miRNA then becomes a part of the RNA-Induced Silencing Complex (RISC) and can bind to the 3' UTR of the target mRNA (3).

Background: Trans-activation response (TAR) RNA binding protein (TRBP2) was initially discovered as a double stranded RNA binding protein (dsRBP) that bound TAR RNA sequences of the HIV-1 virus (1, 2). TRBP2 can bind to and inhibit the phosphorylation of protein kinase PKR, which leads to increased activation of the HIV-1 long terminal repeat (3,4). Along with PACT, TRBP2 is one of the dsRBPs in the RNA-induced silencing complex (RISC), where it plays a critical role in recruiting Ago2 to the miRNA bound by Dicer. (5-8).

Background: PACT (protein activator of protein kinase R) is a double stranded RNA binding protein and a cellular activator of PKR (protein kinase R), a kinase that mediates the antiviral and antiproliferative actions of interferon (1). Stress signals such as serum starvation and arsenite treatment induces PACT to heterodimerize with PKR, resulting in the phosphorylation of eIF-2α and inhibition of protein synthesis (1,2). PACT has also been shown to play a role in RNA-mediated gene silencing by stimulating the activity of Dicer, thereby affecting the efficiency of miRNA accumulation and siRNA gene silencing (3,4). More recently, PACT has been shown to interact with RIG-I, a sensor of viral nucleic acids, and stimulates RIG-I-induced type I interferon production (5). Researchers have found that mutations in PACT are associated with dystonia, a movement disorder where patients develop involuntary muscle contractions and postures (6-8).

Background: Drosha was identified as a nuclear RNase III that catalyzes the initial step of microRNA (miRNA) processing (1). This enzyme processes the long primary transcript pri-miRNAs into stem-looped pre-miRNAs. Interference of Drosha results in the increase of pri-miRNAs and the decrease of pre-miRNAs (1). Drosha exists in a multiprotein complex called Microprocessor along with other components such as DGCR8 (2). Drosha, along with DGCR8, is necessary for miRNA biogenesis (3).

Background: Small non-coding RNAs are important regulators of gene expression in higher eukaryotes (1,2). Several classes of small RNAs, including short interfering RNAs (siRNAs) (3), microRNAs (miRNAs) (4), and Piwi-interacting RNAs (piRNAs) (5), have been identified. MicroRNAs are about 21 nucleotides in length and have been implicated in many cellular processes such as development, differentiation, and stress response (1,2). MicroRNAs regulate gene expression by modulating mRNA translation or stability (2). MicroRNAs function together with the protein components in the complexes called micro-ribonucleoproteins (miRNPs) (2). Among the most important components in these complexes are Argonaute proteins (1,2). There are four members in the mammalian Argonaute family and only Argonaute 2 (Ago2) possesses the Slicer endonuclease activity (1,2). Argonaute proteins participate in the various steps of microRNA-mediated gene silencing, such as repression of translation and mRNA turnover (1).
