Ycf12 has been identified as a core subunit in the photosystem II (PSII) complex [1-2]. PsbZ has been shown to be required for the association of PsbK and Ycf12 with PSII [2].

1: Ycf12 is a core subunit in the photosystem II complex. Kashino Y, Takahashi T, Inoue-Kashino N, Ban A, Ikeda Y, Satoh K, Sugiura M; Biochim Biophys Acta. 2007;1767:1269-1275. PMID:17935689

2: Absence of the PsbZ subunit prevents association of PsbK and Ycf12 with the PSII complex in the thermophilic cyanobacterium Thermosynechococcus elongatus BP-1. Iwai M, Suzuki T, Dohmae N, Inoue Y, Ikeuchi M; Plant Cell Physiol. 2007;48:1758-1763. PMID:17967798
