Mutations (unipCov2Mut) Track Description


This track shows protein sequence annotations from the UniProt/SwissProt database, mapped to genomic coordinates. The data has been curated from scientific publications by the UniProt/SwissProt staff. The annotations are spread over multiple tracks, based on their "feature type" in UniProt:

Track Name Description
UCSC Alignment, SwissProt Protein sequences from SwissProt mapped onto the genome. All other tracks are (start,end) annotations mapped using this track.
UCSC Alignment, TrEMBL Protein sequences from TrEMBL mapped onto the genome. All other tracks are (start,end) annotations mapped using this track. This track is hidden by default. To show it, click its checkbox on the track description page.
UniProt Signal Peptides Regions found in proteins destined to be secreted, generally cleaved from mature protein.
UniProt Extracellular Domains Protein domains with the comment "Extracellular".
UniProt Transmembrane Domains Protein domains of the type "Transmembrane".
UniProt Cytoplasmic Domains Protein domains with the comment "Cytoplasmic".
UniProt Polypeptide Chains Polypeptide chain in mature protein after post-processing.
UniProt Domains Protein domains, zinc finger regions and topological domains.
UniProt Disulfide Bonds Disulfide bonds.
UniProt Amino Acid Modifications Glycosylation sites, modified residues and lipid moiety-binding regions.
UniProt Amino Acid Mutations Mutagenesis sites and sequence variants.
UniProt Protein Primary/Secondary Structure Annotations Beta strands, helices, coiled-coil regions and turns.
UniProt Sequence Conflicts Differences between Genbank sequences and the UniProt sequence.
UniProt Repeats Regions of repeated sequence motifs or repeated domains.
UniProt Other Annotations All other annotations

Display Conventions and Configuration

Genomic locations of UniProt/SwissProt annotations are labeled with a short name for the type of annotation (e.g. "glyco", "disulf bond", "Signal peptide" etc.). A click on them shows the full annotation and provides a link to the UniProt/SwissProt record for more details. TrEMBL annotations are always shown in light blue, except in the Signal Peptides, Extracellular Domains, Transmembrane Domains, and Cytoplamsic domains subtracks.

Mouse-over a feature to see the full UniProt annotation comment. For variants, the mouse-over will show the full name of the UniProt disease acronym.

The subtracks for domains related to subcellular location are sorted from outside to inside of the cell: Signal peptide, extracellular, transmembrane, and cytoplasmic.

In the "UniProt Modifications" track, lipoification sites are highlighted in dark blue, glycosylation sites in dark green, and phosphorylation in light green.


UniProt sequences were aligned to UCSC/Gencode transcript sequences first with BLAT, filtered with pslReps (93% query coverage, within top 1% score), lifted to genome positions with pslMap and filtered again. UniProt annotations were obtained from the UniProt XML file. The annotations were then mapped to the genome through the alignment using the pslMap program. This mapping approach draws heavily on the LS-SNP pipeline by Mark Diekhans. Like all Genome Browser source code, the main script used to build this track can be found on GitHub.

Data Access

The raw data can be explored interactively with the Table Browser or the Data Integrator. For automated analysis, the genome annotation is stored in a bigBed file that can be downloaded from the download server. The exact filenames can be found in the track configuration file. Annotations can be converted to ASCII text by our tool bigBedToBed which can be compiled from the source code or downloaded as a precompiled binary for your system. Instructions for downloading source code and binaries can be found here. The tool can also be used to obtain only features within a given range, for example:

bigBedToBed -chrom=NC_045512v2 -start=0 -end=29903 stdout
