Novel monoclonal antibodies targeting the RRM2 domain of human TDP-43 protein.

ABSTRACT: Transactive response DNA-binding protein of 43 kilodaltons (TDP-43) is a 414 amino acid protein that under physiologic conditions localizes to the nucleus and participates in the regulation of RNA metabolism through two RNA recognition motifs (RRM1 and RRM2). In neurodegenerative diseases, TDP-43 may become hyperphosphorylated, ubiquitinated, and aggregate into cytoplasmic inclusions. TDP-43 is now well-characterized as a pathologic protein of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration with TDP-43 proteinopathy (FTLD-TDP). Additionally, a common TDP-43 proteinopathy arising outside of the context of ALS and FTLD-TDP has been recently described, termed "limbic predominant age-related TDP-43 encephalopathy (LATE)." In the current study, two novel mouse-derived
