Alternative splicing

Biology Altered selfAltruism

Alternative splicing is the RNA splicing variation mechanism in which the exons of the primary gene transcript, the pre-mRNA, are separated and reconnected so as to produce alternative ribonucleotide arrangements.

 


Alternative splicing is the process that occurs in eukaryotes in which the splicing process of a pre-mRNA can lead to different ripe mRNA molecules and therefore to different proteins.

Alternative splicing: Formation of diverse mRNAs through differential splicing of the same RNA precursor. This may result in proteins with different composition of amino acids or it may involve just the length of 3' UTR.

alternative splicing
In alternative splicing, the same pre-mRNA molecule, which consists of introns and exons, is spliced in different ways to produce mature mRNAs of different lengths and different functionality.

Alternative Splicing
The processing of pre-mRNA for many proteins proceeds along various paths in different cells or under different conditions.

Alternative splicing The generation of unique but related mrna molecules by the differential splicing of the pre-mrna transcript.

Alternative splicing
One reason is that one gene may produce more than one mRNA. RNA splicing is the normal process in which intron sequences are removed from the pre-mRNA, producing the mRNA, which corresponds to the exons.

Expression of cathepsin B is regulated at many different levels, from gene amplification, use of alternative promoters, increased transcription and alternative splicing, to increased stability and translatability of transcripts.

Oftentimes, because of alternative splicing, one gene can produce multiple proteins. And of course there are genes that don't even make proteins at all. They make RNAs that have some other functional role.
