The binding of IL-2 to its receptor in an activated T- cell is mediated by
cellular compartmentalization and cell cycle analysis shows SNARE-mediated trafficking, Hayflick limit, P53 and cyclin regulation control proliferation. Consequently α and β chains emerges as the valid choice since it aligns with membrane trafficking and cell cycle control, aligning with established principles in cell biology literature.
Ref: Alberts et al., Molecular Biology of the Cell, 6th Edition, Chapter 17, Cell Cycle and Regulation, explains Cdc2, cyclins, P53, proteasomes, Hayflick limit, primary culture and immortalization mechanisms governing proliferation.
