Experimental Data

Contains experimentally-derived protein half-life data obtained using stable isotope labeling by amino acids (SILAC) coupled with mass spectrometry. This section also contains protein abundance data for both untreated and treated cells obtained from over 20 studies. These data have been normalized and converted to a common unit of molecules per cell.

Domain Locations

Visual representation of the locations of the domains within the protein, as listed in the Domains and Classification table. Each row displays the domain(s) derived from a different Source, with domains color-coded according to this Source.

Scroll over a domain to view its exact coordinates and its Description.

Shared Domains

This diagram displays domains (colored squares) shared between the given protein (yellow circle) and other proteins (gray circles); the domains are color-coded according to their source, as displayed in the Domain Locations table, above.

Reset

Click on a gene or domain name to go to its specific page within SGD; drag any of the gene or domain objects around within the visualization for easier viewing; click “Reset” to automatically redraw the diagram.

Alleles

Curated mutant alleles for the specified gene, listed alphabetically. Click on the allele name to open the allele page. Click "SGD search" to view all alleles in search results.

Sequence

Protein sequence for the given gene in S288C and other strains, when available. Use the pull-down menu under "Strain" to select the sequence for a specific strain. The displayed sequence can be downloaded in FASTA format as a .txt file. Amino acids displayed in blue represent modification sites. More detailed evidence for these modification sites is presented in the Post-translational Modifications table, located just below the protein sequence.
