Product used: Biotinylated human recombinant RalA protein

Application: Biotinylated RalA protein was used in published research investigating whether targetable cryptic switch-II pockets are conserved across Ras-, Rho-, and Rab-family GTPases.

Assay / Workflow:
Pan-GTPase druggability research Cryptic switch-II pocket analysis Small GTPase chemical biology Biotinylated protein assay reagent Small molecule discovery

Key assay details: The study surveyed members of the Ras, Rho, and Rab GTPase families to evaluate conserved cryptic switch-II pocket druggability. The Amid Biosciences product page identifies biotinylated RalA protein as a validated research tool used in this work.

Reported result: The study reported that targetable switch-II pockets are conserved across multiple GTPase family members, supporting broader small-molecule discovery efforts beyond KRAS.
