Anti-SMAD1

In 1X PBS, pH 7.4, with 0.09% sodium azide. 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] Protein function: Transcriptional modulator activated by BMP (bone morphogenetic proteins) type 1 receptor kinase. SMAD1 is a receptor-regulated SMAD (R-SMAD). SMAD1/OAZ1/PSMB4 complex mediates the degradation of the CREBBP/EP300 repressor SNIP1. May act synergistically with SMAD4 and YY1 in bone morphogenetic protein (BMP)-mediated cardiac-specific gene expression. [The UniProt Consortium]
