OHP1_ARATH | developmental stage | Highly expressed in seedling cotyledons and shoot apices in young and mature plants. |
OHP1_ARATH | function | May play a photoprotective role in the thylakoid membrane in response to light stress (Probable). Involved in photosystems I (PSI) and II (PSII) core proteins function (PubMed:29438089). Forms a trimeric complex with OHP2 and HCF244 that is required to promote PSII core subunit assembly (PubMed:29930106, PubMed:30397023). The trimeric complex forms a transient PSII reaction center-like complex with PsbA, PsbD, PsbE, PsbF and PsbI subunits in thylakoids for early assembly of PSII as well as PSII repair (PubMed:30397023). The trimeric complex is required for the recruitment of ribosomes to the psbA mRNA during PSII biogenesis and repair (PubMed:31991763). Forms a heterodimer with OHP1 that binds chlorophylls and carotenoids, and that may function in the delivery of pigments to the PsbA subunit of PSII (PubMed:32071152). |
OHP1_ARATH | similarity | Belongs to the ELIP/psbS family. |
OHP1_ARATH | subcellular location | Associated with both photosystems I and II. |
OHP1_ARATH | tissue specificity | Mostly expressed in cotyledons and shoot apices. |
