PGRL1B PGR5-like B [Arabidopsis thaliana (thale cress)] - Gene

Summary

Official Symbol: PGRL1B
Official Full Name: PGR5-like B
Primary source: TAIR:AT4G11960
Locus tag: AT4G11960
See related: Araport:AT4G11960
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Arabidopsis thaliana (ecotype: Columbia)
Lineage: Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliopsida; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Brassicaceae; Camelineae; Arabidopsis
Also known as: F16J13.30; F16J13_30; PGR5-like B
Summary: Encodes PGRL1B, a transmembrane protein present in thylakoids. PGRL1B has a highly homologous isoform PGRL1A encoded by At4g22890. Plants lacking PGRL1 show perturbation of cyclic electron flow, similar to PGR5-deficient plants. PGRL1 and PGR5 interact physically and associate with PSI (photosystem I).
