Summer 2020 - MBB 430 D100

Mechanisms of Secretory Transport (3)

Class Number: 5670

Delivery Method: In Person


  • Course Times + Location:

    May 11 – Aug 10, 2020: Wed, Fri, 12:30–2:20 p.m.

  • Prerequisites:

    MBB 322 and MBB 331, with a minimum grade of C.



Analysis of mechanisms of protein, lipid, and nucleic acid delivery and transport within cells; processes of protein targeting, exocytosis, and endocytosis; molecular mechanisms of vesicle transport and membrane fusion; role in signal transduction and disease.


Lecture Schedule:
Each week begins with an analysis of a historical “landmark paper” to introduce each topic. This discussion is followed by student seminars that present current aspects of each topic.

Weekly topics:

  1. Introductory lecture. Overview and techniques in molecular cell biology.
  2. Protein targeting, recycling, and retention.
  3. Membrane structure and viral fusagens.
  4. Synaptic exocytosis, and the SNARE hypothesis.
  5. Yeast SEC genes.
  6. Yeast VPS genes.
  7. Clathrin-mediated endocytosis.
  8. Coatamer-mediated (non-clathrin) vesicular transport (COPI and COPII complexes).
  9. Caveolae and membrane rafts.
  10. Autophagy: stress-induced metabolic recycling.
  11. Nonvesicular lipid transfer & membrane contact sites.
  12. Nuclear import and export.

Registrar Notes:


SFU’s Academic Integrity web site is filled with information on what is meant by academic dishonesty, where you can find resources to help with your studies and the consequences of cheating.  Check out the site for more information and videos that help explain the issues in plain English.

Each student is responsible for his or her conduct as it affects the University community.  Academic dishonesty, in whatever form, is ultimately destructive of the values of the University. Furthermore, it is unfair and discouraging to the majority of students who pursue their studies honestly. Scholarly integrity is required of all members of the University.


Please note that all teaching at SFU in summer term 2020 will be conducted through remote methods. Enrollment in this course acknowledges that remote study may entail different modes of learning, interaction with your instructor, and ways of getting feedback on your work than may be the case for in-person classes.

Students with hidden or visible disabilities who believe they may need class or exam accommodations, including in the current context of remote learning, are encouraged to register with the SFU Centre for Accessible Learning ( or 778-782-3112) as soon as possible to ensure that they are eligible and that approved accommodations and services are implemented in a timely fashion.
