Involved in high light-mediated energy-dependent nonphotochemical quenching (NPQ, qE) and thermal dissipation (TD) thus regulating energy conversion in photosystem II and protecting from photoinhibition (PubMed:17459330, PubMed:21804028, PubMed:21873330, PubMed:22413771, PubMed:25342550, PubMed:24850835, PubMed:25306526). Seems also to regulate quantum yield of electron transport in fluctuating light conditions (PubMed:24850835).

Belongs to the ELIP/psbS family.
