This document combines notes from all of the modules in Receptor Signalling in Health and Disease. It includes diagrams, highlighted keywords, and detailed learning objectives.

Lecture notes of LIFE305 Cell Signalling on kinases (e.g. SRC kinase, PKA), phosphatases, ubiquitylation and receptor tyrosine kinases. Lots of background information on the structure and function of these enzymes and their substrates. Also info on protein domains and their role in signalling networks. In-depth info on the ubiquitin cycle.

In-depth lecture notes on the ubiquitin cycle including the principal enzymes (E1, E2, E3), different types of ubiquitin chains and their functions (signalling, proteosomal degradation, trafficking), and crosstalk between ubiquitination and phosphorylation in the NFkB pathway. The NFkB pathway is also discussed in detail (proteins/posttranslational modifications involved, activation of the pathway, negative feedback loop which inhibits the pathway, and a relatively new model of the pathway invol...
