Alternative RNA Splicing02:18

Alternative RNA Splicing

24.5K
Alternative RNA splicing is the regulated splicing of exons and introns to produce different mature mRNAs from a single pre-mRNA. Unlike in constitutive splicing where a single gene produces a single type of mRNA, alternative splicing allows an organism to produce multiple proteins from a single gene and plays an important role in protein diversity.
There are five types of alternative RNA splicing that vary in the ways the pre-mRNA segments are removed or retained in the mature mRNA. The first...

Cis-regulatory Sequences

11.4K
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...

RNA Splicing

60.1K
Splicing is the process by which eukaryotic RNA is edited before its translation into protein. The RNA strand transcribed from eukaryotic DNA is called the primary transcript. The primary transcripts that become mRNAs are called precursor messenger RNAs (pre-mRNAs). Eukaryotic pre-mRNA contains alternating sequences of exons and introns. Exons are nucleotide sequences that code for proteins, whereas introns are the non-coding regions. In RNA splicing, introns are removed and exons are bonded...

Area of Science:

  • Plant molecular biology
  • Genomics
  • Transcriptomics

Background:

  • Alternative splicing (AS) is crucial for transcriptome and proteome diversity, particularly in plants.
  • AS increases functional diversity of proteins and is often tissue-specific.
  • RNA-Seq studies reveal pervasive AS in plant genomes.

Purpose of the Study:

  • To develop a comprehensive database for exploring alternative splicing and tissue-specific splicing events in plants.
  • To integrate genomic annotations, isoform functions, and tissue-specific AS data for cucumbers.
  • To facilitate the discovery of novel functional characteristics arising from AS.

Main Methods:

  • Construction of the cucumber alternative splicing database (CuAS).
  • Integration of genomic annotations, isoform-level functions, features, and tissue-specific AS events.
  • Implementation of a retrieval system for gene and isoform IDs, and a visualization browser.

Main Results:

  • CuAS provides a centralized resource for annotated transcripts from alternative splicing in cucumbers.
  • The database integrates diverse data types, including genomic location and gene family information.
  • Tissue-specific AS events are cataloged for multiple cucumber tissues.

Conclusions:

  • The CuAS database is a valuable tool for investigating AS and tissue-specific splicing in cucumbers.
  • It aids in uncovering novel functional roles of AS-generated isoforms.
  • CuAS is freely accessible for plant research.
