Raf1 from Arabidopsis thaliana consists of an N-terminal alpha-domain, a flexible linker segment and a C-terminal beta-sheet domain that mediates dimerization. The alpha-domains mediate the majority of functionally important contacts with RbcL (Rubisco large subunits) by bracketing each RbcL dimer at the top and bottom. The alpha-domain alone is essentially inactive [1].

Raf1 is necessary for rubisco to catalyze the rate-limiting step of carbon fixation through carboxylating the five-carbon sugar substrate ribulose-1,5-bisphosphate. The beta domains primary function is dimerization, which is critical for Raf1 to achieve the necessary avidity for complex formation with RbcL (the large complex sub-unbit of Rubsico) assembly intermediates. The beta domain is also involved, to a small extent, in binding to RbcL with use of the lustiness near the beta domain's conserved top surface [1].
