Clathrin light chain also known as clathrin LCa and LCb is a low-molecular-weight component of the clathrin protein complex. It plays a mechanical role in the processes that drive clathrin-mediated endocytosis. Each clathrin triskelion the basic unit of the clathrin coat comprises three clathrin heavy chains and three clathrin light chains. The mass of clathrin light chain is approximately 25-29 kDa. This protein is expressed in various tissues throughout the body with notable presence in the central nervous system and liver.

Biological function summary

Clathrin light chain modulates the lattice dynamics by interacting with clathrin heavy chains in a clathrin protein complex. This interaction supports the stability and assembly of the clathrin lattice affecting the efficiency and specificity of endocytic vesicle formation. Clathrin light chain acts in concert with other accessory proteins to regulate clathrin coat assembly and disassembly playing a dynamic role in cellular trafficking processes.

Pathways

The clathrin light chain participates in essential cellular pathways such as the clathrin-mediated endocytosis and synaptic vesicle recycling pathways. These pathways facilitate the internalization and recycling of membrane proteins and lipids ensuring cellular homeostasis. In these processes the clathrin light chain works closely with related proteins such as dynamin and adaptin to control vesicle scission and cargo selection.

Abnormalities in clathrin light chain function connect to neurodegenerative disorders like Huntington's disease and certain types of cancers. In Huntington's disease disrupted endocytic pathways that involve clathrin light chain impact cellular communication and nutrient uptake. Cancer cells may exhibit altered expression or function of clathrin light chain affecting pathways important for cell proliferation and survival. The clathrin light chain can interact with the huntingtin protein in these contexts influencing disease progression and cellular dynamics.
