UniProt functional annotation for P18263



	UniProt functional annotation for P18263

UniProt code: P18263.

Organism: Chlamydomonas reinhardtii (Chlamydomonas smithii).

Taxonomy: Eukaryota; Viridiplantae; Chlorophyta; core chlorophytes; Chlorophyceae; CS clade; Chlamydomonadales; Chlamydomonadaceae; Chlamydomonas.

Function: One of the components of the core complex of photosystem II (PSII). PSII is a light-driven water:plastoquinone oxidoreductase that uses light energy to abstract electrons from H(2)O, generating O(2) and a proton gradient subsequently used for ATP formation. It consists of a core antenna complex that captures photons, and an electron transfer chain that converts photonic excitation into a charge separation. Required for assembly and/or stability of PSII (PubMed:12939265, PubMed:8193302). {ECO:0000255|HAMAP-Rule:MF_00441, ECO:0000269|PubMed:12939265, ECO:0000269|PubMed:8193302}.

Subunit: 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, at least 3 peripheral proteins of the oxygen- evolving complex and a large number of cofactors. It forms dimeric complexes. This protein is tightly associated with CP43 (psbC), one of the core proteins (PubMed:12939265). {ECO:0000255|HAMAP-Rule:MF_00441, ECO:0000269|PubMed:12939265, ECO:0000269|PubMed:1885590}.

Subcellular location: Plastid, chloroplast thylakoid membrane {ECO:0000255|HAMAP-Rule:MF_00441, ECO:0000269|PubMed:12939265, ECO:0000269|PubMed:1885590}; Single-pass membrane protein {ECO:0000255|HAMAP-Rule:MF_00441, ECO:0000305|PubMed:12939265}.

Disruption phenotype: Not able to grow photoautotrophically, grows normally heterotrophically. Accumulates less than 10% PSII, although the subunits are synthesized normally. {ECO:0000269|PubMed:8193302}.

Similarity: Belongs to the PsbK family. {ECO:0000255|HAMAP- Rule:MF_00441}.
