Recognition of human autophagy-related 8 (hATG8) proteins by autophagy receptors represents a critical step within this cellular quality control system. Autophagy impairment is known to be a pathogenic mechanism in the motor neuron disorder amyotroph...

Post-translational modifications (PTMs) enhance the repertoire of protein function and mediate or influence the activity of many cellular processes. The preparation of site-specifically and homogeneously modified proteins, to apply as tools to unders...

Modification of small ubiquitin-related modifier 2 (SUMO2) by phosphoubiquitin in HEK293T cells (2021)
Journal Article
Dongdem, J. T., Dawson, S. P., & Layfield, R. (2021). Modification of small ubiquitin-related modifier 2 (SUMO2) by phosphoubiquitin in HEK293T cells. Proteomics, 21(15), Article 2000234. https://doi.org/10.1002/pmic.202000234

Additional complexity in the post-translational modification of proteins by ubiquitin is achieved by ubiquitin phosphorylation, for example within PINK1-parkin mediated mitophagy. We performed a preliminary proteomic analysis to identify proteins dif... Read More about Modification of small ubiquitin-related modifier 2 (SUMO2) by phosphoubiquitin in HEK293T cells.
