General description
Transactive response DNA-binding protein 43 (TDP-43) belongs to the family of heterogeneous nuclear ribonucleoproteins (hnRNPs). It has two RNA-recognition motifs and a glycine-rich C-terminal sequence. TDP-43 is expressed in heart, lung, liver and brain, which is localized to the nucleus..
Immunogen
synthetic peptide containing phosphorylated Ser409 of human TDP-43 conjugated to KLH. The corresponding sequence is identical in mouse TDP-43
Application
Anti-phospho-TDP-43 [pSer409] antibody produced in rabbit has been used in:
- enzyme linked immuno sorbent assay (ELISA)
- immunohistochemistry
- immunoblotting
- immunofluorescence
Biochem/physiol Actions
Transactive response DNA-binding protein 43 (TDP-43) binds to single stranded RNA. It regulates transcription regulation in human immunodeficiency virus (HIV). TDP-43 is the major ubiquinated component of cytoplasmic inclusions in frontotemporal lobe degeneration subtype (FTLD-U) and amyotrophic lateral sclerosis (ALS). Pathological TDP-43 forms abnormal inclusions in neuronal perikarya and neurites. Mutations in TDP-43 is associated with ALS. Abnormal phosphorylation of TDP-43 at Ser409/410 is observed in FTLD-U and ALS, leading to apoptosis.
Physical form
Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD) are two incurable neurodegenerative disorders that exist on a symptomological spectrum and share both genetic underpinnings and pathophysiological hallmarks. Functional abnormality of TAR DNA-binding protein 43 (TDP-43), an aggregation-prone RNA and
