What molecular mechanisms underlie the differential functional roles of distinct OX2R C-terminal regions?

The study shows that different C-terminal segments (369-384, 385-414, 415-444) have distinct effects on signaling pathways, surface expression, and internalization, but the underlying molecular mechanisms are not explained. Understanding these mechanisms is crucial for targeted therapeutic interventions in orexin-related disorders.
