Smad-anchor for receptor activation
WebPrior to activation, receptor-regulated SMADs are anchored to the cell membrane by factors like SARA (SMAD Anchor for Receptor Activation) that bring the SMADs into proximity of the TGF receptor kinases ( 5 ).

Schematic representation of TGF-β signaling as well as the role of TGF-β signaling pathway in cancer onset and progression.
Smad-anchor for receptor activation
Did you know?
WebSmad anchor for receptor activation (SARA) is an important regulator of transforming growth factor β (TGF-β) signaling by recruiting Smad2/3 to TGF-β receptors. Although TGF-β signaling is critically involved in epileptogenesis, whether SARA activation is sufficient to facilitate TGF-β pathway to regulate epilepsy remains unknown. Methods
WebSmad3 transduces the signals of TGF-βs, coupling transmembrane receptor kinase activation to transcriptional control. The membrane-associated molecule SARA (Smad … TGF-B ligands bind receptors consisting of type 1 and type 2 serine/threonine kinases, which serve to propagate the signal intracellularly. Ligand binding stabilizes a receptor complex consisting of two type 1 receptors, and two type 2 receptors. Type 2 receptors then can phosphorylate type 1 receptors at locations on the GS domain, located N-terminally to the type 1 kinase domain. This phosphorylation event activates the type 1 receptors, making them capable of further propagatin…
WebFeb 5, 2024 · The general canonical view that has been established for TGFβ signaling is that it binds to its cognate type II receptor, which facilitates receptor complex formation and activation of the cytoplasmic serine/threonine kinase activity of the type I receptor leading to phosphorylation of Smad2/3 (receptor regulated Smads: R-Smads). Webfrom the transmembrane serine-threonine receptor kinases to the nucleus. The Smad anchor for receptor activation (SARA) recruits Smad2 to the TGFb re-ceptors for phosphorylation. The crystal structure of a Smad2 MH2 domain in complex with the Smad-binding domain (SBD) of SARA has been determined at 2.2 angstrom resolution.
WebThe receptor-associated Smads (R-Smads: Smad1, 2, 3, 5, and 8) are recruited to the activated TβRI by auxiliary proteins such as Smad Anchor for Receptor Activation (SARA). 31 ALK1, ALK2, ALK3, and ALK6 phosphorylate Smad1, Smad5, and Smad8, whereas ALK4, ALK5, and ALK7 phosphorylate Smad2 and Smad3 ( Fig. 1).
