BLAT can be used for alignments of two protein sequences. However, it is not the tool of choice for these types of alignments. BLASTP, the Standard Protein BLAST tool, is more efficient at protein-protein alignments; [1] Determination of the distribution of exonic and intronic regions of a gene; [9] [10]
On the other hand, the program XNU is used to mask off the tandem repeats in protein sequences. Make a k-letter word list of the query sequence. Take k=3 for example, we list the words of length 3 in the query protein sequence (k is usually 11 for a DNA sequence) "sequentially", until the last letter of the query sequence is included. The ...
Protein A, B and C are isoforms encoded from the same gene through alternative splicing. A protein isoform, or "protein variant", [1] is a member of a set of highly similar proteins that originate from a single gene and are the result of genetic differences. [2] While many perform the same or similar biological roles, some isoforms have unique ...
Alternative splicing produces three protein isoforms.Protein A includes all of the exons, whereas Proteins B and C result from exon skipping.. Alternative splicing, or alternative RNA splicing, or differential splicing, is an alternative splicing process during gene expression that allows a single gene to produce different splice variants.
One way to visualize the similarity between two protein or nucleic acid sequences is to use a similarity matrix, known as a dot plot. These were introduced by Gibbs and McIntyre in 1970 [1] and are two-dimensional matrices that have the sequences of the proteins being compared along the vertical and horizontal axes.
It makes use of the BLAST [5] algorithm to identify similar sequences to then transfers existing functional annotation from yet characterised sequences to the novel one. The functional information is represented via the Gene Ontology (GO), a controlled vocabulary of functional attributes.
A part of a multiple sequence alignment of four different hemoglobin protein sequences. Similar protein sequences, usually indicate shared functions. Proteins of similar sequence are usually homologous [5] and thus have a similar function. Hence proteins in a newly sequenced genome are routinely annotated using the sequences of similar proteins ...
First 90 positions of a protein multiple sequence alignment of instances of the acidic ribosomal protein P0 (L10E) from several organisms. Generated with ClustalX. Multiple sequence alignment (MSA) is the process or the result of sequence alignment of three or more biological sequences, generally protein, DNA, or RNA.
