ABSTRACT:
Ion channels are one of the largest drug targets likely due to their role in regulation and signal transduction. KCNQ1 is a voltage-gated potassium channel associated with cardiac arrhythmias such as Long-QT syndrome. Several structures of the voltage sensing domain (VSD) or the pore domain have been resolved; however, there are no known structures of a resting VSD. In order to understand the mutational effects, the inactive VSD, closed pore state of KCNQ1 was modeled using Rosetta. RosettaCM enables the use of multiple templates in addition to fragment insertion during homology modeling. Knowledge from experimental studies of the charged residue pairing placement in the VSD was used as a filter during model selection. Finally, MolProbity, ProCheck, and PoreWalker were used to further assess the quality of the selected models.
Several methods exist for modeling mutation-induced stability changes from proteins of known structure or homology models; however, many of these methods perform poorly for membrane proteins. The amount of mutant thermostability data that is available for membrane proteins is sparse, making it nearly impossible to train an accurate predictor for the stabilizing effects of mutations. In a membrane protein benchmark, Rosetta outperformed most of the 10 methods assessed and was able to correctly classify nearly 70% of mutations as destabilizing. Combining these modeling efforts may help with identifying disease-associated mutations in the future. Cyrus Bench is capable of rapidly assessing the stabilizing effects of single point mutations using the newest Rosetta scoring function and thoroughly benchmarked protocols.
