STE20-related kinase adapter protein beta (STRADB)

Pseudokinase which, in complex with CAB39/MO25 (CAB39/MO25alpha or CAB39L/MO25beta), binds to and activates STK11/LKB1. Adopts a closed conformation standard of protein kinases and binds STK11/LKB1 for a pseudosubstrate, promoting conformational change of STK11/LKB1 in an active conformation (By similarity).
