RI and RII receptors are homodimeric proteins with serine/threonine kinases in their cytosolic domains. 

(RI and RII sufficient to serve as a functional hetero-tetrameric TGF-β receptor)

The activity of rubisco is also regulated by light, but the enzyme itself does not respond to thioredoxin.

Two protons are released during the formation of the ternary complex rubisco–CO2–Mg2+, so activation is promoted by an increase in both pH and Mg2+ concentration.
