Characteristics of Non-coding RNA

Among many types of ncRNAs, microRNAs (miRNAs), in particular, have been studied and identified as important components of post-transcriptional gene silencing (He & Hannon 2004). Other ncRNA sets such as snoRNA, piRNA, large intergenic noncoding RNA (lincRNA), and heterologous long noncoding RNA (lncRNA) also play a role in chromosome remodeling, splicing, transcription, RNA editing, and translation be able to. Inhibition, mRNA destruction and cellular stress response (Esteller 2011).

Noncoding RNA (ncRNA) is an RNA molecule that is not translated into protein. DNA sequences which are functionally transcribed by noncoding RNA are generally referred to as RNA genes. Abundant and functionally important noncoding RNA types include transfer RNA (tRNA) and ribosomal RNA (rRNA), as well as long x cRNA such as microRNA, siRNA, piRNA, snoRNA, snRNA, exRNA, scaRNA and Xist and HOTAIR Small RNA is included. The number of noncoding RNAs in the human genome is unknown; however, recent transcriptome and bioinformatics studies have shown that there are thousands of them. Many newly discovered ncRNAs have not yet been validated by their function. Many ncRNAs also may not function (also called junk RNA), a product of mis-transcription.

Small noncoding RNA is up to 200 bases of RNA that is unlikely to encode protein. These are microRNAs or miRNAs (posttranscriptional regulators of gene expression), small nuclear RNA or snRNA (RNA component of splice), small nucleolar RNA or snoRNA (involved in direct chemical modification of other RNA molecules) including. Long noncoding RNA is an RNA molecule longer than 200 bases that is unlikely to encode protein. These include ribosomal RNA or rRNA (RNA component of ribosomes) and various other long RNAs involved in regulating gene expression, epigenetic modification of DNA nucleotides and histone proteins, and regulating activities encoding proteins included. The small difference in the sum between the gene ncRNA number and the specific type of small ncNRA derives from the former value from Ensembl version 87, the latter value from Ensembl version 68.

Small regulated RNA contains a specific class of RNA that affects gene regulation. These RNAs are typically highly structured and are small noncoding RNA molecules consisting of many stem loops. These small regulatory RNAs play an important role in gene regulation through a number of mechanisms. Small mechanisms that regulate RNA function include binding to protein targets, protein modification, binding to mRNA targets, and regulation of gene expression. There are many types of small regulatory RNAs that play an important role in regulation.
