Smad transcription factors are central to the signal transduction pathway that mediates the numerous effects of the TGF-β superfamily of cytokines in metazoan embryo development and adult tissue regeneration and homeostasis. Although Smad proteins are conserved, recent genome-sequencing projects have revealed their sequence variation in metazoan evolution, human polymorphism, and cancer. Structural studies of Smads bound to partner proteins and target DNA provided a framework to understand the significance of these evolutionary and pathologic sequence variations. Here we synthesize the extant mutational and structural data to suggest how genetic variation in Smads may affect the structure, regulation, and function of these proteins. Furthermore, we present a web-app that compares Smad sequences and displays Smad protein structures and their disease-associated variants.
