Concept Info

NAME

Non-coding RNAs

DESCRIPTION

Non-coding RNAs (ncRNAs) are ribonucleic acid (RNA) molecules that are not translated into protein products. Different classes of non-coding RNAs participate in different cellular processes; for example, gene expression regulation (miRNAs, piRNAs, lncRNAs), RNA maturation (snRNAs, snoRNAs) and protein synthesis (rRNAs, tRNAs).

JSON-LD is the canonical representation for SciGraph data.

TIP: You can open this SciGraph record using an external JSON-LD service: JSON-LD Playground Google SDTT

14 skos:definition Non-coding RNAs (ncRNAs) are ribonucleic acid (RNA) molecules that are not translated into protein products. Different classes of non-coding RNAs participate in different cellular processes; for example, gene expression regulation (miRNAs, piRNAs, lncRNAs), RNA maturation (snRNAs, snoRNAs) and protein synthesis (rRNAs, tRNAs).

40 skos:definition Long non-coding RNAs (lncRNA) are a type of non-coding RNAs (ncRNAs) that exceed 200 nucleotides in length. lncRNAs are a relatively abundant component of the mammalian transcriptome and have been implicated in several cellular functions, including the regulation of gene transcription through the recruitment of chromatin-modifying enzymes.

60 skos:definition micro RNAs (miRNAs) are a type of non-coding RNA (ncRNA), ~21–24 nucleotides in length, that function in the post-transcriptional regulation of gene expression. Typically miRNAs interact with specific mRNAs through complementary base-pairing to influence the translation or stability of the target mRNA molecule.

145 skos:definition siRNAs (small interfering RNAs) are double-stranded RNA molecules 20–25 bases in length with 2 nucleotide overhangs that are produced through the enzymatic cleavage of longer precursor RNAs by the ribonuclease Dicer. siRNAs can limit the expression of specific genes by targeting their RNA for destruction through the RNA interference (RNAi) pathway.
