ABL1 Myristoyl Pocket

Molecular classification
Protein Domain, Allosteric regulatory site
01

Overview

The ABL1 myristoyl pocket is a deep hydrophobic cavity located in the C-lobe of the kinase domain of the ABL1 protein. It plays a crucial regulatory role by binding to either an N-terminal myristoyl group or small-molecule inhibitors, which induces conformational changes and stabilizes an autoinhibited state, reducing kinase activity. Targeting this site offers therapeutic potential for overcoming resistance seen with traditional ATP-site tyrosine kinase inhibitors.
