Welcome to Cytology – Lecture 15: Other Cellular Organelles and Cell Junctions, where we explore lesser-known but biologically important components of the eukaryotic cell.
This lecture focuses on proteasomes, vaults, and their roles in cellular organization, transport, and regulation, along with an overview of cell junctions that maintain tissue integrity.

🎯 Topics Covered:
• Overview of cytosol and non-membranous organelles
• Proteasomes:
– Structure and distribution in the cytoplasm
– Role in protein degradation
– Breakdown of misfolded, abnormal, and unnecessary proteins
– Ubiquitin-dependent protein recycling
– Importance in cell regulation and disease prevention
• Vaults (Ribonucleoprotein Particles):
– Discovery and structure
– Association with lipid rafts
– Role in nuclear-cytoplasmic transport
– Major vault protein (MVP), VPARP, and TEP1
– Vault RNA component
– Involvement in drug resistance, signaling, immunity, and cancer
• Introduction to cell junctions and their importance in tissue organization
• Functional significance of cellular organelles in maintaining cell homeostasis

💡 Why Watch:
This lecture is essential for students studying cytology, cell biology, zoology, biomedical science, and molecular biology, helping you understand how cells regulate proteins, transport molecules, and maintain structural coordination.
