CAB39 (Calcium Binding Protein 39) is a Protein Coding gene. Among its related pathways are RET signaling and AMP-activated Protein Kinase (AMPK) Signaling. Component of a complex that binds and activates STK11/LKB1. In the complex, required to stabilize the interaction between CAB39/MO25 (CAB39/MO25alpha or CAB39L/MO25beta) and STK11/LKB1.
