High-light-induced proteins are small proteins mostly located in Photosystem II.
Hlips bind chlorophyll and β-carotene and are related to plant LHCII antennae.
Hlips protect machinery for synthesis of chlorophyll–proteins.
Hlips quench energy absorbed by chlorophylls via transfer to S1 state of β-carotene.
Hlips are involved in reuse of chlorophyll after chlorophyll–protein degradation.
