product information

PGRL1 is a transmembrane protein present in thylakoids of higher plants and algae. Arabidopsis plants lacking PGRL1 show perturbation of cyclic electron transport (CEF) around photosystem I (PSI), similar to PGR5-deficient plants. PGRL1 has been shown to interact physically with PGR5 and associate with PSI (DalCorso et al., 2008). In Chlamydomonas reinhardtii, PGRL1 is part of a protein supercomplex, composed of PSI with its own light-harvesting complex (LHCI), the photosystem II light-harvesting complex (LHCII), the cytochrome b6/f complex (Cyt b6f), ferredoxin (Fd)-NADPH oxidoreductase (FNR), responsible of the energy balance of the two photosystems and of the switch between thylakoid linear and cyclic electron transport (Iwai et al., 2010). Synonymes:


the N-terminal loop (aa 61 to 200; N-PGRL1) of PGRL1A (Q8H112, At4g22890). The N-PGRL1 protein was purified by virtue of its His-Tag using Ni-NTA Agarose (QIAGEN).

Host Rabbit
Clonality Polyclonal

application example

5 µg of chlorophyl a/lane from Arabidopsis thaliana wild-type thylakoids (1), Arabidopsis thaliana pgr5 mutant thylakoids (2), Arabidopsis thaliana double mutant thylakoids (3), were separated on 12% SDS-PAGE and blotted 1h to nitrocellulose membrane.Blots were blocked immediately following transfer with 5% dry milk in 1x TBS together with 0.1% Tween-20 (1x TBS-T) for 1h at room temperature with agitation. Blots were incubated in the primary antibody at a dilution of 1:3000 for 2h at room temperature with agitation. The antibody solution was decanted and the blot washed three times, 10 min each, with 1x TBS-T at room temperature with agitation. Blots were incubated in secondary antibody (anti-rabbit horseradish peroxidase conjugated, from Pierce) diluted to 1:50.000 for 1h at room temperature with agitation. The blots were washed as above and developed for 5 min with ECL detection reagent according to the manufacturer’s instructions. Exposure time was 5 min.
