BIOL4041: CELL SIGNALS AND PROTEIN TARGETTING (MSCI)

Prerequisites

• Molecular Biology BIOL2201 and Cell Structure and Function BIOL2211.

Corequisites

• None.

Excluded Combination of Modules

• None.

Aims

• To promote an appreciation of the molecular events occurring in cells upon receipt of an external signal.
• To appreciate how proteins are targeted to different organelles and how these targeting events respond to cell signals.
• To conduct an investigation into a topic on cell signals OR protein targeting where knowledge obtained by a literature search is important.
• To appreciate how failures in cellular organisation can impact on the health of humans and other organism.

Content

• The secretory pathway.
• Lysosomes, Vesicles.
• Coatomers.
• Clathrin.
• Genetics of secretion.
• Mitochondria.
• Peroxisomes.
• Nuclear import.
• Targeting of proteins to plastids.
• Biology of inorganic carbon.
• Bicarbonate and sperm maturation.
• Carbon dioxide and pathogenesis.
• Carbon dioxide activated signalling.
• Biology of Na.
• GAF domains and Na signalling.
• Plant cell Signals: Introduction to plant signalling mechanics.
• Light in plant development.
• mechanisms of hormone action.
• diversity of action and the 'new' plant hormones.

Learning Outcomes

• Students should be able to: Demonstrate a knowledge and understanding of the molecular events involved in cell signalling.
• demonstrate a knowledge and understanding of the molecular events involved in protein targeting.
• understand that these processes are linked and form part of the homeostasis of the cell.

• be able to design an experimental strategy to investigate an aspect of cell signalling or protein targeting.

• extract, compile and review relevant scientific information from various sources and evaluate them critically.
• acquire, interpret and critically analyse experimental and clinical data and present the results effectively.

Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

• Taught compoent: Teaching and learning in this component is primarily through means of lectures.
• MCQs are appropriate as a revision aid and to demonstrate knowledge acquisition.
• The data handling exercise will show the ability to interpret data and develop presentation skills.
• The integration of these skills will be assessed in the written examination.
• Skills will be acquired through the searching, retrieval and presentation of relevant data.
