Which European genome browser is listed with UCSC as presenting HGP data? The answer is Ensembl.
Ensembl is a genome database and browser project created through collaboration between the European Bioinformatics Institute and the Wellcome Trust Sanger Institute. It was launched in 1999, as researchers prepared for the Human Genome Project’s draft and the need to annotate the sequence became urgent.
Its central job is to connect genome assemblies with biological interpretation. Ensembl provides gene models, transcripts, comparative genomics, variation data, regulatory annotations and downloadable sequence information. Researchers can search a gene, inspect its location, compare related species and examine alternative transcripts or known variants.
Ensembl and the UCSC Genome Browser are complementary resources, not two names for the same website. Both display genome coordinates and annotations, but their pipelines, releases and presentation differ. RefSeq is a curated sequence reference collection, PubMed is a scientific-literature database, and UniProt focuses primarily on protein knowledge. Those resources may be linked from genome browsers, but they are not the European browser named in the question.
