Neuronal Puncta/Aggregate Formation by WT and Mutant UBQLN2

Methods Mol Biol. 2023:2551:561-573. doi: 10.1007/978-1-0716-2597-2_34.

Abstract

Protein aggregates are a common feature of nearly all neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis (ALS). Here we describe a method to quickly and accurately measure protein aggregation in cells expressing a fluorescently tagged aggregation-prone protein. This unbiased method obviates the need for manual scoring and facilitates the identification of factors governing protein self-assembly and its downstream consequences for cell heath.

Keywords: Longitudinal microscopy; Neurodegeneration; Protein aggregation; Proteostasis; Single cell.
