The UCSC Genome Browser provides flexible access to genomic sequences and aligned annotation tracks (known genes, predicted genes, ESTs, mRNAs, CpG islands, assembly gaps and coverage, chromosomal bands, mouse homologies, and more) for over 40 model organisms. It can also be used for visualizing, comparing and analyzing both publicly available and user-generated genomic data sets.
Genome Browser: visualize genomic sequence and annotation tracks
Table Browser: text-based access to the database underlying the Genome Browser
Custom Tracks: upload user data to the Genome Browser and overlay user data with existing/custom annotation tracks
BLAT: a fast sequence alignment tool similar to BLAST
Gene Sorter: retrieve genes with similar features (e.g. expression profiles, homology, protein family, etc.)
In-Silico PCR: quick search of the genome with PCR primer pairs.
Liftover: converts genome coordinates and genome annotation files between assemblies
Proteome: protein information search hub
Human ENCODE projects: fully searchable ENCODE data and display at UCSC genome browser
