General annotation (Comments)

Function

Probably participates in efficiency of electron transfer from plastocyanin to P700 (or cytochrome c553 in algae and cyanobacteria). This plastocyanin-docking protein contributes to the specific association of plastocyanin to PSI.

Subcellular location

Plastidchloroplast thylakoid lumen.

Sequence similarities

Belongs to the PsaF family.
