Protein LOW PSII ACCUMULATION 3 (LPA3) is probably located in chloroplast stroma or associated with thylakoid membranes. LPA3 works cooperatively with LPA2 as auxiliary proteins in the incorporation of psbC (also known as CP43) into PSII via interaction with cpSRP translocase ALB3. They are thought to be also involved in synthesis and assembly of psbC [ 1 ].
