UniProtKB description:  One of the components of the core complex of photosystem II (PSII). PSII is a light-driven water:plastoquinone oxidoreductase that uses light energy to abstract electrons from H(2)O, generating O(2) and a proton gradient subsequently used for ATP formation. It consists of a core antenna complex that captures photons, and an electron transfer chain that converts photonic excitation into a charge separation. This subunit is found at the monomer-monomer interface. Probably involved in dimerization of PSII; at the monomer-monomer interface the only protein-protein contacts observed are between the 2 PsbM subunits. Lipids, chlorophylls and carotenoids contribute strongly to PSII dimerization.
