CC   -!- FUNCTION: The light-harvesting complex (LHC) functions as a light
CC       receptor, it captures and delivers excitation energy to
CC       photosystems with which it is closely associated.
CC   -!- COFACTOR: Binds at least 14 chlorophylls (8 Chl-a and 6 Chl-b) and
CC       carotenoids such as lutein and neoxanthin (By similarity).
CC   -!- SUBUNIT: The LHC complex consists of chlorophyll a-b binding
CC       proteins.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane;
CC       Multi-pass membrane protein.
CC   -!- TISSUE SPECIFICITY: Present at high levels in leaves and
CC       cotyledons.
CC   -!- INDUCTION: Markedly increased by light.
CC   -!- DOMAIN: The N-terminus of the protein extends into the stroma
CC       where it is involved with adhesion of granal membranes and post-
CC       translational modifications; both are believed to mediate the
CC       distribution of excitation energy between photosystems I and II.
CC   -!- PTM: Photoregulated by reversible phosphorylation of its threonine
CC       residues (By similarity).
CC   -!- SIMILARITY: Belongs to the light-harvesting chlorophyll a/b-
CC       binding (LHC) protein family.
