Small rna function
WebA significant fraction of genes in most organisms and tissues is targets of these small ncRNAs. Because these tiny RNAs are turning out to be important regulators of gene and genome expression, their aberrant expression profiles are expected to be associated with cellular dysfunction and disease. WebNov 1, 2010 · 1. Introduction. The first small RNA, lin-4, was discovered in 1993 through a genetic screening in nematodes.Later in the same year, the regulation of lin-14 by lin-4 was discovered, which demonstrated the regulatory function of small RNAs [1], [2].The shorter lin-4 RNA is now recognized as the origin of an abundant class of small regulatory RNAs, …
