LTPG1 glycosylphosphatidylinositol-anchored lipid protein transfer 1 [Arabidopsis thaliana (thale cress)] - Gene

Summary

Official Symbol: LTPG1
Official Full Name: glycosylphosphatidylinositol-anchored lipid protein transfer 1
Primary source: TAIR:AT1G27950
Locus tag: AT1G27950
See related: Araport:AT1G27950
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: F13K9.6; F13K9_6; glycosylphosphatidylinositol-anchored lipid protein transfer 1
Summary: Encodes LTPG1, a lipid transfer protein with a predicted GPI (glycosylphosphatidylinositol)-anchor domain. Localized in the plasma membrane. Disruption of the LTPG1 gene causes alterations of cuticular lipid composition, but no significant changes on total wax and cutin monomer loads are seen.
