Western blot shows recombinantDrosophilaSmad2 (2 ng/lane). PVDF membrane was probed with 0.1 µg/mL of Sheep Anti-DrosophilaSmad2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7948) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Smad2 (C-terminal fragment) at approximately 25 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background

Smad2 (SMAll body plus Mothers Against Decapentaplegic; also SmoX [Smad on Chr X]) is a 54 kDa (predicted) member of the receptor regulated Smad family of proteins. It is a downstream component of the Drosophila activin/TGF beta signaling pathway, and appears to play a key role in cell proliferation. Analogous to the system in vertebrates, stimulation of the fruitfly activin type I receptor (baboon):type II receptor (punt) complex results in dSmad2 (Drosophila Smad2) phosphorylation and subsequent interaction with dSmad4/Medea. As in vertebrates, the Drosophila Samd2/Smad4 complex enters the nucleus and interacts with a transcriptional cofactor(s) termed TGIF. At this point, the vertebrate:invertebrate systems diverge over the nature of the TGIF cofactor(s); vertebrate TGIF is a corepressor, while invertebrate TGIF (dTGIF) is a coactivator. Drosophila Smad2 is 486 amino acids (aa) in length. It contains two Mad homology domains (aa 7-130 and 285-475), the former of which participates in DNA-binding. Over aa 262-486, Drosophila Smad2 shares 70% aa sequence identity with both mouse and human Smad2.
