| Function: | |
The light-harvesting complex (LHC) functions as a light receptor, it captures and delivers excitation energy to photosystems with which it is closely associated. {ECO:0000269|PubMed:21806943}. |
|
||
| Cofactor: | |
Note=Binds at least 14 chlorophylls (8 Chl-a and 6 Chl-b) and carotenoids such as lutein and neoxanthin. {ECO:0000269|PubMed:15563470, ECO:0000269|PubMed:21083539}; |
| Subunit: | |
The LHC complex consists of chlorophyll a-b binding proteins. Red-emitting heterodimer with LHCA4 (PubMed:21083539). Interacts with LHCA5 (PubMed:21806943, PubMed:15563470). {ECO:0000269|PubMed:15563470, ECO:0000269|PubMed:21083539, ECO:0000269|PubMed:21806943}. |
| Subcellular location: | |
Plastid, chloroplast thylakoid membrane {ECO:0000269|PubMed:10818090}; Multi-pass membrane protein {ECO:0000255}. |
| Induction: | |
Induced by low light (LL) but repressed by high light (HL). Inhibited by cold. {ECO:0000269|PubMed:15356385}. |
| Domain: | |
The N-terminus of the protein extends into the stroma where it is involved with adhesion of granal membranes and post-translational modifications; both are believed to mediate the distribution of excitation energy between photosystems I and II. |
| Ptm: | |
Photoregulated by reversible phosphorylation of its threonine residues. {ECO:0000250}. |
| Miscellaneous: | |
Light emission at 684 nm upon excitation at 410 and 470 nm. {ECO:0000269|PubMed:15563470}. |
| Similarity: | |
Belongs to the light-harvesting chlorophyll a/b-binding (LHC) protein family. {ECO:0000305}. |
