Determining the effects of loss of function mutations in human cell lines

Abstract

Summary: Quantifying differences in the amount of protein and mRNA caused by missense mutations in a gene of interest can be challenging, especially when using patient-derived primary cells, which are intrinsically variable. In this protocol, we describe how to culture patient-derived lymphoblast and fibroblast cell lines for later mRNA and protein quantification. We also describe the steps to examine variants of PUM1 in HEK293T cells, but the protocol can be applied to other proteins of interest.For complete details on the use and execution of this protocol, please refer to Gennarino et al. (2018).
