Whole-cell abundance profiling and interaction analysis of UBQLN2

Version 1

This project serves as a centralized repository for omics datasets published by research groups within the SyNergy Cluster. It encompasses investigations such as proteomics and transcriptomics, which are further divided into individual studies led by SyNergy members. Each study is linked to relevant publications, assays and data files (with links to external repositories).

Ubiquilin-2 (UBQLN2) is a ubiquitin-binding protein that shuttles ubiquitinated proteins to proteasomal and autophagic degradation. UBQLN2 mutations are genetically linked to the neurodegenerative disorders amyotrophic lateral sclerosis and frontotemporal dementia (ALS/FTD). However, it remains elusive how UBQLN2 mutations cause ALS/FTD. Here, we systematically examined proteomic and transcriptomic changes in patient-derived lymphoblasts and CRISPR/Cas9-engineered HeLa cells carrying ALS/FTD ...

LCL cells were cultured in lysine- and arginine-free DMEM (GIBCO) supplemented with 2 mM glutamine, 10% dialyzed FBS and antibiotics as well as with 146 mg/ml light (K0, Sigma) or heavy lysine (K8, Cambridge Isotope Laboratories) and 84 mg/ml light (R0, Sigma) or heavy (R10, CambridgeIsotope Laboratories) arginine, respectively. Cell pellets were lysed in 8 M Urea in 50 mM Tris-HCl pH 8.0. Protein concentrations were determined by a BCA assay and protein amounts were adjusted to equal concentrations. ...
