TGF-β Receptor 1 (TGFBR1) is a transmembrane serine/threonine kinase that serves as the primary type I receptor for transforming growth factor-beta ligands in the nervous system. This protein plays critical roles in mediating TGF-β signaling that regulates neuroinflammation, neuronal survival, synaptic plasticity, and glial function.
TGFBR1 (Transforming Growth Factor Beta Receptor 1) is a 53 kDa transmembrane receptor kinase that transduces extracellular TGF-β signals into cellular responses[1]. As the primary type I receptor, TGFBR1 phosphorylates downstream SMAD proteins (SMAD2/3) to regulate gene expression programs controlling neuronal survival, neuroinflammation, and synaptic plasticity[2].
