Protein attributes

Sequence length	473 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	One of the components of the core antenna complex of photosystem II. It binds chlorophyll and helps catalyze the primary light-induced photochemical processes of photosystem II By similarity. Interacts with PAM68.
Subunit structure	PSII consists of a core antenna complex that captures photons, and an electron transfer chain that converts photonic excitation into a charge separation. PSII forms dimeric complexes By similarity.
Subcellular location	Plastid › chloroplast thylakoid membrane; Multi-pass membrane protein Probable.
Post-translational modification	Phosphorylation occurs in normal plant growth light conditions. Rapid dephosphorylation occurs during heat shock.
Sequence similarities	Belongs to the PsbB/PsbC family. PsbC subfamily.
Sequence caution	The sequence BAA84381.2 differs from that shown. Reason: Erroneous gene model prediction.
