- The molecular basis for clathrin function.
- Clathrin proteins' roles in physiology, including lymphocyte function, glucose metabolism and oncogenesis, and potential therapeutic value.
- The genetic diversity and evolutionary origins of the clathrin proteins, and the functional consequences of clathrin subunit diversity.
Towards these goals, we employ a range of scientific techniques, including biochemical analysis, protein production and purification, mass spectrometry, tissue culture and cellular assays, electron and confocal light microscopy, physiological models and human and evolutionary genetics.
In 2014, Professor Brodsky moved from the University of California San Francisco to join UCL as Director of the Division of Biosciences, finishing her second term as Director in December 2020. The laboratory fully relocated to UCL in 2015 and is part of the Department of Structural and Molecular Biology in the Division of Biosciences, where Brodsky continues her research programme and teaching.
"Studying the remarkable self-assembling clathrin proteins has led us in diverse research directions, crossing interfaces between biochemistry, cell biology, immunology and metabolism. It is exciting and gratifying that our basic molecular studies are now revealing intracellular mechanisms and pathways that are directly relevant to several human diseases including infection, type 2 diabetes and cancer." - Frances Brodsky
Clathrins for Non-Scientists
At the Brodsky Lab, we are passionate about making our research as widely available and understood as possible. We have "translated" what our lab does into language we hope anyone can understand.
The Brodsky laboratory has made significant contributions to understanding the structure, function and regulation of clathrin proteins. Research in the laboratory continues to investigate novel and conventional clathrin functions that are important for human health. Specifically, the lab is currently focussing on the following projects:
Project #1 – CHC22-dependent trafficking of the insulin-sensitive GLUT4 glucose transporter
Humans have two isoforms of the clathrin heavy chain (CHC), known as CHC17 and CHC22. CHC17 is ubiquitously expressed and is involved in a wide range of intracellular trafficking activities, most notably receptor-mediated endocytosis. In contrast, CHC22 is primarily expressed in muscle cells and performs a more specialised function in trafficking the GLUT4 glucose transporter to an insulin-sensitive, intracellular storage compartment. Whilst CHC17 has been extensively studied, much less is known about how CHC22 operates. One of the main research activities of our lab is utilising a combination of structural biology, biochemistry, genomics and cell biology to elucidate the mechanism, function, and regulation of CHC22 and its dependent pathways.

Project #2 – Physiological functions of the clathrin light chains
The canonical form of clathrin is composed of CHC17 and clathrin light chains (CLCs). CLCs bind in a 1:1 stoichiometric ratio with CHC17 and are known to be required for the endocytosis of some (but not all) cargo to modulate the biophysical properties of clathrin (such as the ability of clathrin to deform membranes) and to mediate protein-protein interactions. However, the full scope of CLC functions remain to be defined. In particular, CLCs are encoded by two genes, which give rise to CLCa and CLCb, and tissue specific splice variants of these genes, resulting in a total of six CLC isoforms. CLCa and CLCb share about 60% identity, and each isoform and their tissue-specific distribution are conserved throughout mammalian species, suggesting that the CLC isoforms perform non-redundant, tissue specific roles. We are interested in understanding how diversity amongst the CLCs allows clathrin function to be fine-tuned to meet tissue-specific physiological needs.
