This track contains deep mutational scanning data measuring the effect of the change in expression, ACE2 or antibody binding from a wild type allele to a mutant allele. The authors use a yeast display system to experimentally measure the effect of all possible point (amino acid) RBD mutations on protein expression, ACE2 affinity or antibody binding.
Each subtrack contains all the scores representing mutations to a particular amino acid (each annotation is a S codon). For instance the A subtrack measures the change in expression of S RBD expression if the annotated amino acid is mutated to alanine (if the wildtype amino acid is A, then the score is 0). A positive score indicates increased expression a negative score is a loss of expression.

Table S2 from Starr et al, was downloaded and parsed into bedGraph format using the average value of both replicates reported. All NA values were filtered out.
The raw data can be explored interactively with the Table Browser, or combined with other datasets in the Data Integrator tool.
