Alternative splicing is one of the most important mechanisms to generate a large number of mRNA and protein isoforms from the surprisingly low number of human genes. Alternative splicing is a post-transcriptional process that occurs in different stresses, developmental conditions and in different cell types (reviewed by Wang et al., 2008; Staiger and Brown, 2013; Li et al., 2016). Alternative splicing expands the coding capacity of metazoan genes, and it was largely genetic studies in the fruit-fly Drosophila melanogaster that established the principle that regulated alternative splicing results in tissue- and stage-specific protein isoforms with different functions in development. Unlike promoter activity, which primarily regulates the amount of transcripts, alternative splicing changes the structure of transcripts and their encoded proteins. Alternative splicing is one of the most important mechanisms to generate a large number of mRNA and protein isoforms from the surprisingly low number of human genes. Alternative splicing, or the splicing out of different introns in different transcripts of the same genetic material, functions to allow for the giant diversity of protein sequences using smaller amounts of genes.

The function of these three GAP peptides from the lamprey GNRH-1 gene is unknown, but the single GAP peptide cleaved from the human GNRH precursor protein can inhibit secretion of lutenizing hormone (LH), follicle stimulating hormone (FSH), and prolactin from … Alternative splicing factors regulate multiple pre-mRNAs and recent identification of physiological targets shows that a specific splicing factor regulates pre-mRNAs with coherent biological functions. Alternative splicing is coordinated by a variety of factors, including genomic structure characteristics, TPP riboswitches, splicing factors and DNA methylation, and is involved in the regulation of growth and development, and the improvement of survivability and pathogenicity. Unlike promoter activity, which primarily regulates the amount of transcripts, alternative splicing changes the structure of transcripts and their encoded proteins. Alternative splicing changes proteins encoded by mRNAs, which has profound functional effects. However, alternative splicing also frequently controls output levels and spatiotemporal features of cellular and organismal gene expression programs. ► Changes caused by alternative splicing are usually small. The magnitude of the effects range from a complete loss of function or acquisition of a new function to very subtle modulations, which are observed in the majority of cases reported. Therefore, evidence is now accumulating that alternative splicing coordinates physiologically meaningful changes in protein isoform expression and is a key mechanism to generate the complex proteome of multicellular organisms. The overall function of alternative splicing is to increase the diversity of mRNAs expressed from the genome. Abstract Alternative pre-mRNA splicing plays important roles in co-transcriptional and post-transcriptional regulation of gene expression functioned during many developmental processes, such as spermatogenesis. These cis-acting regulatory elements alter splicing by binding different trans-acting protein factors, such as SR (Serine-Arginine rich) proteins that function as splicing facilitators, and heterogeneous nuclear ribonucleoproteins (hnRNPs) that suppress splicing. Unlike promoter activity, which primarily regulates the amount of transcripts, alternative splicing changes the structure of transcripts and their encoded proteins. Molecular analyses during the last decade demonstrate that alternative splicing determines the binding properties, intracellular localization, enzymatic activity, protein stability and posttranslational modifications of a large number of proteins. versatile … By continuing you agree to the use of cookies.
