Course Aims

This course aims to introduce students to the different steps proteins are engaged through the secretory and endocytic pathways. You will learn detailed molecular processes part of the secretory and endocytic pathways. The ultimate goal of this course is to make you grasp the fine line between cellular homeostasis and cellular states leading to the development of diseases from secreted and membrane proteins.

Intended Learning Outcomes

Upon successfully completing this course, you should be able to:

  1. Analyse and solve problems related to protein secretion
  2. Interpret data focusing on protein processing and transport
  3. Hypothesise possible reasons for defect in protein processing and transport
  4. Suggest experiments to verify hypotheses regarding protein processsing and transport
  5. Synthesise complex protein processing concepts into concise answers

Course Content

Overview of the Endoplasmic Reticulum (ER), phospholipid biosynthesis, and transport

Targeting proteins to the ER, translocation, and membrane protein topology

Protein folding and protein quality control in the ER

Vesicle transport focusing on ER-Golgi trafficking

Endocytosis and polarized delivery of proteins

Formative Feedback

Discussion in class from students answers and burning questions from students on the Readiness Assurance Tests (quiz) gives students feedback on learning outcome 1.

Discussion in class on the different answers of application exercises from different teams. General questions related to the application exercises will also be discuss in class provides feedback on learning outcomes 1, 2, 3, 4, and 5.

General questions related to the application exercises will also be discussed in class, which helps students to achieve learning outcomes 1, 2, 3, 4, and 5.

Learning and Teaching Approach

Lectures
(26 hours)

Multiple Choices Questions: The students are required to read and study lecture material, related discussion, and related reading and then complete shot MCQ quizzes in class. These help students achieve learning outcomes 1 and 2.

Final 2-hour written examination: individual examination will contain short answer questions only. These help students achieve learning outcomes 1, 2, 3, 4 and 5.

Tutorials
(13 hours)

Application Exercises (essays): in-class activities to solved problems as a team which requires the utilization of the concepts discuss in lectures. The exercises will be designed to lead to multiple possible answers to avoid rigid right/wrong answer and to encourage inter- and intra-team discussions. These help students achieve learning outcomes 1, 2, 3, 4 and 5.

Course Policies and Student Responsibilities

Students are required to go through and understand the pre-class material (6 in total over the semester) that will be available in NTULearn prior to class.

Students are expected to attend class every week to take part of the "Readiness Assurance Test" and/or "Application Exercises".

Students are expected to be engaged within their working team and in class.

Academic Integrity

Good academic work depends on honesty and ethical behaviour. The quality of your work as a student relies on adhering to the principles of academic integrity and to the NTU Honour Code, a set of values shared by the whole university community. Truth, Trust and Justice are at the core of NTU’s shared values.

As a student, it is important that you recognize your responsibilities in understanding and applying the principles of academic integrity in all the work you do at NTU. Not knowing what is involved in maintaining academic integrity does not excuse academic dishonesty. You need to actively equip yourself with strategies to avoid all forms of academic dishonesty, including plagiarism, academic fraud, collusion and cheating. If you are uncertain of the definitions of any of these terms, you should go to the Academic Integrity website for more information. Consult your instructor(s) if you need any clarification about the requirements of academic integrity in the course.
