Biosignaling - TGF-β Signaling Pathway

The video explains the TGF beta signaling pathway, highlighting its similarity to receptor tyrosine kinases (RTKs). It covers the role of TGF beta receptors, kinase domains, and the phosphorylation process that activates SMAD proteins. These proteins form a complex that enters the nucleus to influence gene transcription. The video concludes with a brief mention of the next topic, Hedgehog signaling.
