Summary

Go to the top of the page Help

Official Symbol: JAC1
Official Full Name: J-domain protein required for chloroplast accumulation response 1
Primary source: TAIR:AT1G75100
Locus tag: AT1G75100
See related: Araport:AT1G75100
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: F9E10.5; F9E10_5; J-domain protein required for chloroplast accumulation response 1
Summary: Contains a J-domain at the C-terminus which is similar to the J-domain of auxilin, a clathrin-uncoating factor in cow, yeast and worm. Arabidopsis contains 6 other proteins similar to auxilin. Expressed in leaves and stems, but not in roots. Localized in the cytoplasm. Required for the chloroplast accumulation response, but not for the avoidance response. No molecular function known.
