TAR DNA-binding protein 43 (TDP-43) is a ubiquitously expressed RNA-binding protein encoded by the *TARDBP* gene. It plays critical roles in RNA metabolism, including splicing, transport, and stability. Pathologically, TDP-43 is a major component of aberrant protein aggregates observed in neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS), frontotemporal lobar degeneration (FTLD-TDP), and Alzheimer’s disease. In these conditions, TDP-43 undergoes mislocalization from the nucleus to the cytoplasm, forming hyperphosphorylated, ubiquitinated inclusions that disrupt cellular function and contribute to neurodegeneration.
Antibodies targeting TDP-43 are essential tools for studying its physiological and pathological roles. They enable detection of both normal nuclear TDP-43 and pathological aggregates in tissues or cell models using techniques like immunohistochemistry, Western blotting, or immunofluorescence. Specific antibodies can distinguish between normal and disease-associated forms (e.g., phosphorylated or truncated TDP-43), aiding in disease diagnosis and mechanistic research. Additionally, TDP-43 antibodies are used to explore its interactions with RNA or other proteins, its role in stress granule dynamics, and the effects of *TARDBP* mutations linked to familial ALS.
Challenges include ensuring antibody specificity due to post-translational modifications or structural changes in pathological TDP-43. Despite this, these antibodies remain vital for advancing understanding of TDP-43 proteinopathies and developing targeted therapies.
