Black Diamond's MAP Platform
Black Diamond Therapeutics has developed a proprietary method to discover, uncover, and target allosteric mutant oncogenes.
Black Diamond Therapeutics is using its MAP platform to extend its approach to developing drugs to a range of high value oncogenic targets.

The Science of Black Diamond
What is an allosteric mutation?
An allosteric mutation occurs distal to the site of action of an enzyme or receptor. In receptor tyrosine kinases, allosteric mutations occur distal to the the ATP binding site.
Because large-scale conformational changes in proteins are a prerequisite for dimerization in oncogenic RTKs, allosteric mutations most frequently occur at, and structurally alter, the dimerization interface.
How are allosteric mutations oncogenic?
Allosteric mutations activate tumor drivers and inactivate tumor suppressors through the large scale conformational change.
How are allosteric mutations oncogenic in RTKs?
Allosteric mutations render RTK oncogenes ligand-independent.
Consequences of Allosteric Oncogenic Mutations In EGFR AND HER2
For the ErbB RTK oncogenes, EGFR and HER2, the selectivity of the ATP site is altered in comparison to the wild type receptors. Even though there is no change in the primary sequence of the ATP site, allosteric mutant ErbB RTKs exhibit unique drug selectivity.
