Intracellular transport in mammalian cells through vesicular fusion is regulated by which among the following GTPases?
cellular compartmentalization and cell cycle analysis shows SNARE-mediated trafficking, Hayflick limit, P53 and cyclin regulation control proliferation. Consequently Rab 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.
