Web tools for the alignment of multiple biological sequences (protein or nucleic acid). From the output, homology can be inferred. Visual depictions of the alignment can illustrate events such as point mutations, insertions, deletions, etc. Useful in assessing conservation of domains, tertiary/secondary structures, residues or nucleotides.
BLAST
Web tool for finding regions of similarity between biological sequences; nucleotide/protein, various genomes, complex queries. Useful in identifying any sequences that resemble query sequence.
PRIDE
Repository of proteomics data
Ensembl
Alternative splicing and isoform annotation integrated with the Ensembl genome browser. Minimal set of compatible isoforms derived for each gene.
Alternative Splicing Gallery (ASG)
Splice graphs of human genes.
RNAcentral
Unified access to the ncRNA sequence data supplied by the Expert Databases: ENA, Rfam, RefSeq, Vega, gtRNAdb, miRBase, RDP, tmRNA Website, PDBe, snOPY, SRPDB, IncRNAdb.
Entrez Gene
Unified query environment for genes. Gene integrates information from a wide range of species. A record may include nomenclature, Reference Sequences (RefSeqs), maps, pathways, variations, phenotypes, and links to genome-, phenotype-, and locus- specific resources worldwide. Entrez integrates the scientific literature, DNA and protein sequence databases, 3D protein structure and protein domain data, population study datasets, expression data, assemblies of complete genomes, and taxonomic information.
