This track shows protein sequence annotations from the UniProt/SwissProt database,
mapped to genomic coordinates. It shows how the protein sequences in this database
map to the genome. This mapping was used to "lift" the UniProt protein
annotations to the SARS-CoV-2 genome. The protein annotation themselves have been
curated from scientific publications by the UniProt/SwissProt staff.
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.
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.
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. For human and mouse, the
alignments were filtered by retaining only proteins annotated with
a given transcript in the Genome Browser table kgXref. Like all Genome Browser
source code, the main script used to build this track can be found on

For automated analysis, the genome annotation is stored in a bigBed file that

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
The tool can also be used to obtain only features within a given range, for example:
