RT   "Loss of Albino3 leads to the specific depletion of the light-harvesting
RT   system.";
RL   Plant Cell 14:2303-2314(2002).
CC   -!- FUNCTION: Required for the insertion of some light-harvesting complexes
CC       (LHC) proteins into the chloroplast thylakoid membrane. Essential for
CC       the assembly and activity of LHC I and II. Its function is probably
CC       partly distinct from that of ALB3.2. {ECO:0000269|PubMed:12215522}.
CC   -!- SUBUNIT: Associates with the LHCII complex and with the psaE subunit of
CC       the LHCI complex.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC       {ECO:0000269|PubMed:12215522}; Multi-pass membrane protein
CC       {ECO:0000269|PubMed:12215522}.
CC   -!- SIMILARITY: Belongs to the OXA1/ALB3/YidC (TC 2.A.9.2) family.
CC       {ECO:0000305}.
