Ensembl provides a genome browser that acts as a single point of access to annotated genomes, primarily for vertebrate species (Figure 1).
Information such as gene sequence, splice variants and further annotation can be retrieved at the genome, gene and protein level. This includes information on protein domains, genetic variation, homology, syntenic regions and regulatory elements. Coupled with analyses such as whole genome alignments and the effects of sequence variation on proteins, this powerful tool aims to describe a gene or genomic region in detail.
