Abstract

Signaling by receptors from the transforming growth factor-β (TGF-β) superfamily plays critical roles in multiple physiological and pathological processes. Their signaling requires complex formation between type I and type II receptors with Ser/Thr kinase activity, whereby the type II receptor phosphorylates and activates the relevant type I receptor(s), which transduces downstream signaling. It is therefore important to study complex formation among receptors from this family. In the current chapter, we use the type I (ALK5) and type II TGF-β receptors (TβRI and TβRII) as an example for measuring complex formation among cell-surface receptors in live cells by patch-FRAP, a variation of fluorescence recovery after photobleaching (FRAP).
