This SMAD1 antibody was produced from a rabbit immunized with a KLH conjugated synthetic peptide between 163-196 amino acids from the Central region of human SMAD1.
SMADs are intracellular proteins that transduce extracellular signals from transforming growth factor beta ligands to the nucleus where they activate downstream gene transcription. The SMADs, which form a trimer of two receptor-regulated SMADs and one co-SMAD, act as transcription factors that regulate the expression of certain genes. There are three classes of SMADs, SMAD1 belongs to the receptor-regulated class (R-SMAD) which includes SMAD2, SMAD3, SMAD5 and SMAD8/9. [Wiki]
