Smad2 pathway
Smads are roughly between 400 and 500 amino acids long, and consist of two globular regions at the amino and carboxy termini, connected by a linker region. These globular regions are highly conserved in R-Smads and Co-Smads, and are called Mad homology 1 (MH1) at the N-terminus, and MH2 at the … Visa mer Smads (or SMADs) comprise a family of structurally similar proteins that are the main signal transducers for receptors of the transforming growth factor beta (TGF-B) superfamily, which are critically important for … Visa mer The components of the TGF-beta pathway and in particular, the R-Smads, Co-Smad and I-Smads, are represented in the genome of all metazoans sequenced to date. The level of sequence conservation of the Co-Smad and of R-Smads proteins across species is … Visa mer In adult cells, TGF-β inhibits cell cycle progression, stopping cells from making the G1/S phase transition. This phenomenon is present in the epithelial cells of many organs, … Visa mer The R-Smads consist of Smad1, Smad2, Smad3, Smad5 and Smad8/9, and are involved in direct signaling from the TGF-B receptor. Visa mer Before Smads were discovered, it was unclear what downstream effectors were responsible for transducing TGF-B signals. Smads were first … Visa mer R/Co-Smads TGF-B ligands bind receptors consisting of type 1 and type 2 serine/threonine kinases, which serve to propagate the signal intracellularly. Ligand … Visa mer Role of Smad in cancer Defects in Smad signaling can result in TGF-B resistance, causing dysregulation of cell growth. Deregulation of TGF-B signaling has been implicated in many cancer types, including pancreatic, colon, breast, lung, and … Visa mer WebbUsing proteomics coupled to analysis of genome occupancy, we uncover a regulatory complex composed of transcriptional effectors of the Hippo …
