| UniProt code: Q9SPI9. |
|
||
| Organism: | |
Chlamydomonas reinhardtii (Chlamydomonas smithii). |
| Taxonomy: | |

| Function: | |
Stabilizes dimeric photosystem II (PSII). In its absence there is a reduction of monomeric PSII (By similarity). {ECO:0000250|UniProtKB:Q39194}. |
|
||
| Subunit: | |
Part of the photosystem II complex. PSII is composed of 1 copy each of membrane proteins PsbA, PsbB, PsbC, PsbD, numerous small proteins, at least 3 peripheral proteins of the oxygen-evolving complex and a large number of cofactors. It forms dimeric complexes. {ECO:0000269|PubMed:12856936, ECO:0000269|PubMed:1885590}. |
| Subcellular location: | |
Plastid, chloroplast thylakoid membrane {ECO:0000269|PubMed:12856936, ECO:0000269|PubMed:1885590}; Single-pass membrane protein. Note=The N-terminus is found within the thylakoid lumen (By similarity). {ECO:0000250|UniProtKB:Q41387}. |
| Developmental stage: | |
Present in dark-grown plants it increases upon exposure to light. {ECO:0000269|PubMed:12856936}. |
| Similarity: | |
Belongs to the psbW family. {ECO:0000305}. |
