CC   -!- FUNCTION: The light-harvesting complex (LHC) functions as a light
CC       receptor, it captures and delivers excitation energy to photosystems
CC       with which it is closely associated (By similarity). Mediates rapid
CC       phosphorylation and migration of LHCII-PSII to photosystem I (PSI)
CC       after transition to state 2 (red) light conditions, thus leading to the
CC       formation of PSI-PSII-LHCII and PSI-LHCII supercomplex to balance the
CC       relative excitation of PSI and PSII (PubMed:23995216, PubMed:23888908,
CC       PubMed:25194026, PubMed:26392145). Involved in the production of
CC       reactive oxygen species (ROS) and stomatal closure upon abscisic acid
CC       (ABA) treatment. Required to prevent water loss (By similarity).
CC       {ECO:0000250|UniProtKB:P27521, ECO:0000250|UniProtKB:Q9S7J7,
CC       ECO:0000269|PubMed:23888908, ECO:0000269|PubMed:23995216,
CC       ECO:0000269|PubMed:25194026, ECO:0000269|PubMed:26392145}.
CC   -!- COFACTOR:
CC       Note=Binds at least 14 chlorophylls (8 Chl-a and 6 Chl-b) and
CC       carotenoids such as lutein and neoxanthin.
CC       {ECO:0000250|UniProtKB:P12333};
CC   -!- SUBUNIT: The LHC complex consists of chlorophyll a-b binding proteins
CC       (By similarity). Component of LHCII trimers made of LHCB1, LHCB2 and
CC       LHCB3 subunits (PubMed:23888908, PubMed:23995216, PubMed:25194026).
CC       Associated with super- (PSI-LHCII and PSII-LHCII) and mega-complexes
CC       (PSI-PSII-LHCII) containing LHCII and both photosystem (PS)I and PSII,
CC       in state 2 (red) light conditions (PubMed:23995216, PubMed:23888908,
CC       PubMed:25194026, PubMed:26392145). {ECO:0000250|UniProtKB:P12333,
CC       ECO:0000269|PubMed:23888908, ECO:0000269|PubMed:23995216,
CC       ECO:0000269|PubMed:25194026, ECO:0000269|PubMed:26392145}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast thylakoid membrane
CC       {ECO:0000269|PubMed:23995216}; Multi-pass membrane protein
CC       {ECO:0000255}.

CC       Name=2;
CC         IsoId=Q9XF87-2; Sequence=VSP_058661;
CC   -!- INDUCTION: Accumulates at stronger levels in low light than in normal
CC       or high light; more expressed in growth chamber conditions than when
CC       grown in the field (PubMed:22236032). Repressed in leaves exposed to
CC       desiccation, cold and high irradiance via a metalloprotease-dependent
CC       proteolytic process (at protein level) (PubMed:23598180). Activated by
CC       BZIP68 and GBF1 but repressed by BZIP16 (PubMed:22718771).
CC       {ECO:0000269|PubMed:22236032, ECO:0000269|PubMed:22718771,
CC       ECO:0000269|PubMed:23598180}.
CC   -!- PTM: Photoregulated by reversible but rapid phosphorylation by STN7 of
CC       its threonine residues under state 2 (red) light conditions
CC       (PubMed:23995216, PubMed:23888908, PubMed:26392145). Dephosphorylated
CC       by PPH1 in state 1 (far red) light conditions (PubMed:20176943,
CC       PubMed:23995216, PubMed:23888908, PubMed:26392145). Phosphorylation
CC       triggers the formation of the PSI-LHCII supercomplex (PubMed:26392145).
CC       {ECO:0000269|PubMed:20176943, ECO:0000269|PubMed:23888908,
CC       ECO:0000269|PubMed:23995216, ECO:0000269|PubMed:26392145}.
CC   -!- DISRUPTION PHENOTYPE: In plants silenced with microRNAs, functional
CC       LHCII thylakoid protein complexes where LHCB2 is replaced by LHCB1.
CC       However these LHCII complexes are impaired in light state transitions,
CC       leading to stunted growth in high light. {ECO:0000269|PubMed:25194026}.
CC   -!- SIMILARITY: Belongs to the light-harvesting chlorophyll a/b-binding
CC       (LHC) protein family. {ECO:0000305}.
