UniProt functional annotation for Q8DIQ0

UniProt code: Q8DIQ0.

Organism: Thermosynechococcus elongatus (strain BP-1).
Taxonomy: Bacteria; Cyanobacteria; Synechococcales; Synechococcaceae; Thermosynechococcus.
 
Function: Seems to play a role in the dimerization of PSII. PSII is a light-driven water plastoquinone oxidoreductase, using light energy to abstract electrons from H(2)O, generating a proton gradient subsequently used for ATP formation. {ECO:0000255|HAMAP-Rule:MF_00808, ECO:0000269|PubMed:15653799, ECO:0000269|PubMed:20558739, ECO:0000269|PubMed:21367867, ECO:0000269|PubMed:25006873}.
 
Cofactor: Note=PSII binds multiple chlorophylls, carotenoids and specific lipids. {ECO:0000269|PubMed:14764885, ECO:0000269|PubMed:16355230, ECO:0000269|PubMed:17935689, ECO:0000269|PubMed:17967798, ECO:0000269|PubMed:19219048, ECO:0000269|PubMed:20558739, ECO:0000269|PubMed:21367867, ECO:0000269|PubMed:22665786, ECO:0000269|PubMed:23413188, ECO:0000269|PubMed:25006873, ECO:0000269|PubMed:25043005};
Subunit: Cyanobacterial PSII is composed of 1 copy each of membrane proteins PsbA, PsbB, PsbC, PsbD, PsbE, PsbF, PsbH, PsbI, PsbJ, PsbK, PsbL, PsbM, PsbT, PsbX, PsbY, PsbZ, Ycf12, 3 peripheral proteins PsbO, PsbU, PsbV and a large number of cofactors. It forms dimeric complexes. {ECO:0000269|PubMed:14764885, ECO:0000269|PubMed:16355230, ECO:0000269|PubMed:19219048, ECO:0000269|PubMed:20558739, ECO:0000269|PubMed:21367867, ECO:0000269|PubMed:22665786, ECO:0000269|PubMed:23413188, ECO:0000269|PubMed:25006873, ECO:0000269|PubMed:25043005}.
Subcellular location: Cellular thylakoid membrane {ECO:0000255|HAMAP- Rule:MF_00808, ECO:0000269|PubMed:14764885, ECO:0000269|PubMed:16355230, ECO:0000269|PubMed:17935689, ECO:0000269|PubMed:17967798, ECO:0000269|PubMed:19219048, ECO:0000269|PubMed:20558739, ECO:0000269|PubMed:21367867, ECO:0000269|PubMed:22665786, ECO:0000269|PubMed:23413188, ECO:0000269|PubMed:25006873, ECO:0000269|PubMed:25043005}; Single-pass membrane protein {ECO:0000255|HAMAP-Rule:MF_00808, ECO:0000269|PubMed:14764885, ECO:0000269|PubMed:16355230, ECO:0000269|PubMed:17935689, ECO:0000269|PubMed:17967798, ECO:0000269|PubMed:19219048, ECO:0000269|PubMed:20558739, ECO:0000269|PubMed:21367867, ECO:0000269|PubMed:22665786, ECO:0000269|PubMed:23413188, ECO:0000269|PubMed:25006873, ECO:0000269|PubMed:25043005}.
Mass spectrometry: Mass=3906; Mass_error=4; Method=MALDI; Evidence={ECO:0000269|PubMed:19219048};
Mass spectrometry: Mass=3904; Method=MALDI; Evidence={ECO:0000269|PubMed:20558739};
Disruption phenotype: No detectable dimeric PSII, loss of another protein that may be PsbM. {ECO:0000269|PubMed:15653799}.
Similarity: Belongs to the PsbT family. {ECO:0000255|HAMAP- Rule:MF_00808}.
