    Protocol

    Specificity / Sensitivity

    Phospho-TDP43 (Ser409/Ser410) (F9S3F) Rabbit Monoclonal Antibody recognizes endogenous levels of TDP43 protein only when phosphorylated at Ser409/Ser410. This antibody is not recommended for immunohistochemical analysis of mouse tissues.

    Species Reactivity:

    Human, Mouse

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser409/Ser410 of human TDP43 protein.

    Background

    TDP43 (TAR DNA-binding protein 43) is involved in transcriptional regulation and exon splicing (1,2). While normal TDP43 is a nuclear protein, pathological TDP43 is a component of insoluble aggregates in patients with frontotemporal lobar degeneration (FTLD) and amyotrophic lateral sclerosis (ALS). In these disorders, TDP43 is abnormally ubiquitinated, phosphorylated, and cleaved to generate carboxy-terminal fragments that are sequestered as insoluble aggregates in neuronal nuclei, perikarya, and neurites (3,4). Additionally, TDP43 inhibits the expression of the HIV-1 gene and regulates CFTR gene splicing (1,5).

    Phosphorylation of full-length and carboxy-terminal fragments of TDP43 at Ser409/Ser410 is a hallmark of TDP43 proteinopathies (6,7).
