2. Besides the component related relationships from literature, gene mapped protein and protein mapped gene are also shown in the network. If the mapped gene or protein is not from literature, square node would be used instead of Circle node. Accordingly, the relationship is marked with dot line.
2. User can drag the nodes to rearrange the layout of the network. Click the node will enter the report page of the node. Right-click will show also the menus to link to the report page of the node and remove the node and related edges. Hover the node will show the level of the node and hover the edge will show the evidence/description of the edge.
3. The network is generated using Cytoscape Web

REACT_12417	microrna biogenesis	1. Transcription. MicroRNA (miRNA) transcripts may come from...... 1. Transcription. MicroRNA (miRNA) transcripts may come from autonomously transcribed genes or they may be contained in cotranscripts with other genes. Most miRNAs are transcribed by RNA polymerase II, however a few miRNAs originate as RNA polymerase III cotranscripts with neighboring repetitive elements. The initial transcript, termed a primary microRNA (pri-miRNA), contains an imperfectly double-stranded region within a hairpin loop. Longer sequences extend from the 5' and 3' ends of the hairpin and may also contain double-stranded regions. 2. Cleavage by Drosha. The 5' and 3' ends of the pri-miRNA are removed during endoribonucleolytic cleavage by the Drosha nuclease in a complex with the RNA-binding protein DGCR8 (the Microprocessor complex). The cleavage product is a short hairpin of about 60 to 70 nt called the pre-microRNA (pre-miRNA). 3. Nuclear export by Exportin-5. The resulting pre-miRNA is bound by Exportin-5 in a complex with Ran and GTP. The complex translocates the pre-miRNA through the nuclear pore into the cytoplasm. 4. Cleavage by Dicer. Once in the cytoplasm the pre-miRNA is bound and cleaved by the Dicer ribonuclease in complex with the RNA-binding protein TRBP (TAR binding protein). The product is an imperfectly double-stranded miRNA of about 21 to 23 nucleotides. At this stage the double-stranded miRNA has protruding single-stranded 3' ends of 2-3 nt. 5. Strand selection and incorporation into RNA-Induced Silencing Complex (RISC). At this stage the miRNA has two strands: the passenger strand, which will be removed and degraded, and the guide strand, which will be retained and guides the RISC to target mRNAs. An Argonaute protein is already bound to the Dicer:miRNA complex or subsequently binds the complex (the order is unknown). The human genome encodes 4 Argonaute proteins, however only Argonaute2 can cleave target mRNAs with perfect or nearly perfect complementarity to the guide miRNA. In mammalian cells, such endogenous interactions are very rare; most miRNAs only cause translational repression. For complexes that contain Argonaute2, cleavage of the passenger strand of the double-stranded miRNA accompanies removal of the passenger strand. Complexes containing other Argonautes may use a helicase to remove the passenger strand but this is not fully known. The resulting single-stranded miRNA (the guide strand) remains in a complex containing Argonaute, Dicer, TRBP, and other proteins termed the RNA-induced Silencing Complex (RISC). The full set of proteins composing RISC is not yet known. More...
