Anti-phospho-TDP-43 [pSer409] antibody produced in rabbit，200UL，SAB4200223-200UL，Sigma

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 Ser^409/410 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.
