AlphaFold Protein Structure
AlphaFold, developed by DeepMind, is an AI program that accurately predicts protein structures from amino acid sequences, enabling visualization of protein conformations. The predicted structures can be accessed through the Protein Data Bank (PDB) and AlphaFold Protein Structure Database.
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.

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.
