piRNA - Piwi-interacting RNAs02:57

piRNA - Piwi-interacting RNAs

7.6K
PIWI-interacting RNAs, or piRNAs, are the most abundant short non-coding RNAs. More than 20,000 genes have been found in humans that code for piRNAs while only 2000 genes have been found for miRNAs. piRNAs can act at the transcriptional and post-transcriptional levels and have a vital role in silencing transposable elements present in germ cells. They are also involved in epigenetic silencing and activation. Previously, they were thought to function only in germ cells but new evidence suggests...

Cis-regulatory Sequences02:02

Cis-regulatory Sequences

11.8K
Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...

siRNA - Small Interfering RNAs

18.6K
Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...

lncRNA - Long Non-coding RNAs02:39

lncRNA - Long Non-coding RNAs

9.9K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Area of Science:

  • Molecular Biology
  • Genetics
  • Biochemistry

Background:

  • Beyond messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA), non-coding RNAs (ncRNAs) play crucial regulatory roles.
  • ncRNAs, lacking protein-encoding open reading frames, function as riboregulators, primarily mediating posttranscriptional gene expression control.
  • These molecules are vital in prokaryotes and eukaryotes for target recognition, cell growth, differentiation, and are implicated in developmental disorders.

Purpose of the Study:

  • To review existing biochemical and structural data on regulatory non-coding RNAs (ncRNAs).
  • To highlight the diverse mechanisms and functions of ncRNAs in gene regulation.
  • To underscore the versatility of ncRNAs in cellular processes.

  • Literature review of biochemical data.
  • Analysis of structural data for known regulatory RNAs.
  • Synthesis of information on ncRNA functions and mechanisms.

Main Results:

  • ncRNAs exhibit diverse lengths and functions, including riboregulation and protein activity modulation.
  • They recognize nucleic acid targets via complementary base pairing, influencing gene expression.
  • Some ncRNAs are linked to abnormalities in imprinted inheritance and developmental disorders.

Conclusions:

  • Regulatory RNAs are flexible and versatile molecules with diverse roles in cellular regulation.
  • Understanding ncRNA structure and function is key to deciphering complex gene expression networks.
