Signal peptide, CUB and EGF-like domain-containing protein 3 (SCUBE3)

Binds to TGFBR2 and activates TGFB signaling.

In lung cancer cells, could serve as an endogenous autocrine and paracrine ligand of TGFBR2, which might regulate TGFBR2 signaling and thus modulate epithelial-mesenchymal transition and cancer development.
