TGFB1 / TGF Beta 1
Predicted Molecular Weight
Transforming Growth Factor beta 1 comes as a dimer having a 112/224 amino acid chain. Transforming growth factor-beta 1 (TGF-b1) is a member of the TGF-beta superfamily of cytokines. Members of this family exhibit regulatory activity in immunity, proliferation, adhesion, migration, and growth inhibition pathways. TGF-b1 signals through SMAD proteins via the TGF-bRI and TGF-bRII receptors.
