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 ...

MIRN21 was one of the first mammalian microRNAs identified. The mature miR-21 sequence is strongly ...
miR-92 is part of a large precursor sequence that forms a stem loop once transcribed into RNA. This long precursor sequence is a component of the mir-17-92 cluster which contains 5 additional mir precursor sequences: mir-17, mir-18a, mir-19a, mir-20a and mir19b-1. [4]
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.
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.
It is concluded that the miRNA has an important function in the central pacemaker of the Drosophila circadian rhythm clock. To be more precise Bantam miRNA has an important relation with the clock component clk, thus making it an important factor of study regarding its role in Drosophila behavior.
This angiogenic role could implicate miR-132 in oncogenesis, and this miRNA is known to be overexpressed in chronic lymphoblastic leukaemias. [13] miR-132 also comprises part of the recently identified miRNA 'signature' of mammalian osteosarcoma, although a direct role in oncogenesis is yet to be fully described. [14]
