[5] ACVR1C is a type I receptor for the TGFB family of signaling molecules.

[5] ACVR1C transduces signals of Nodal.

Nodal binds to ACVR2B and then forms a complex with ACVR1C.

[6] Upon ligand binding, type I receptors phosphorylate cytoplasmic SMAD family transcription factors, which then translocate to the nucleus and interact directly with DNA or in complex with other transcription factors.
