Comments [?]

Function A major RuBisCO chaperone. Acts after GroEL-GroES chaperonin to fold and/or assemble the large subunit of RuBisCO (ccbL, rbcL). Cooperates with RbcX in RbcL folding, plays the major role in assembly of dimers into RbcL(8)-Raf1(8) intermediate complexes. RbcS replaces Raf1, leading to holoenzyme formation.
Subunit Homodimer. Forms an RbcL(8)-Raf1(8) complex. Forms complexes of many stoichiometries with RbcL with and without RbcS. RbcX and Raf1 can bind simultaneously to RbcL.
Subcellular location Cytoplasm.
Domain Has 3 domains, the N-terminal alpha-helical domain, an extended flexible linker and the C-terminal beta-sheet domain. The 2 C-terminal beta-sheet domains are swapped and pack against each other to form the dimer interface.
Similarity Belongs to the RAF family.
