Members of the Argonaute (Ago) protein family are central to RISC function. Argonautes are needed for miRNA-induced silencing and contain two conserved RNA binding domains: a PAZ domain that can bind the single stranded 3' end of the mature miRNA and a PIWI domain that structurally resembles ribonuclease-H and functions to interact with the 5 ...

MicroRNAs function to regulate the expression levels of other genes by several mechanisms. mir-221 is an oncogenic microRNA. [1] It targets CD117, which then prevents cell migration and proliferation in endothelial cells. [2] [3] miR-221 is known as an anti angiogenic miRNA.

Mir-1 plays an important role in some cancers. Rhabdomyosarcoma is the most common soft tissue sarcoma in children. Since the tumor results from undifferentiated cells, agents that promote differentiation hold promise as possible therapies.
An miRNA that remains constant in its expression through these stages is proposed to have a role in regulating general aspects of cell physiology. [8] Thus it was becoming evident in 2003 shortly after its discovery, that the mir-92 miRNA and associated family members are providing functional roles to the cell cycle and to cell signalling, and ...
