Protein Sorting and the Secretory Pathway | Cell Biology | CSIR NET Life Sciences How are proteins transported from the Endoplasmic Reticulum (ER) to the Golgi complex and finally delivered to their correct destinations inside or outside the cell? In this video, we explore the protein sorting mechanism and the endomembrane system, focusing on the secretory pathway, ER–Golgi transport, Golgi-mediated protein modification, and lysosomal targeting. 🔬 Topics Covered in This Video: 1. Protein Sorting – How proteins are directed to their specific cellular destinations. 2. Secretory Pathway – The journey of newly synthesized proteins through the endomembrane system. 3. Endoplasmic Reticulum (ER) – Protein synthesis, folding, and initial modifications in the rough ER. 4. ER–Golgi Transport – Vesicular transport of proteins from the ER to the Golgi complex. 5. Golgi Complex – Protein modification, processing, sorting, and packaging. 6. Lysosomal Targeting – How lysosomal enzymes are sorted and transported to lysosomes, including the role of mannose-6-phosphate (M6P). 7. Vesicular Transport – How transport vesicles bud from and fuse with membrane-bound compartments. 8. Protein Secretion – How proteins reach the plasma membrane or are released outside the cell. 🎯 Useful for: CSIR-NET Life Sciences GATE Life Sciences MSc and BSc Zoology/Botany Cell Biology and Molecular Biology Competitive examinations in Biological Sciences Understand the complete journey of proteins through the secretory pathway with clear explanations of the ER, Golgi complex, vesicular transport, and lysosomes.
