This study delves into the impact of Mannose-6-Phosphate (Man-6-P) receptors on cellular mechanisms, focusing on their function at acidic pH levels. Analysis reveals associations with endocytosis, degradation, apoptosis, and transcription, shedding light on the intricate cellular pathways involved. The role of Man-6-P receptors alongside other proteins in endosomes, lysosomes, Golgi, and the ER is explored, emphasizing their influence in cellular homeostasis and fate. Findings suggest a pivotal role in regulating crucial processes within the intracellular environment.
