BON3 Calcium-dependent phospholipid-binding Copine family protein [Arabidopsis thaliana (thale cress)] - Gene

Summary

Official Symbol: BON3
Official Full Name: Calcium-dependent phospholipid-binding Copine family protein
Primary source: TAIR:AT1G08860
Locus tag: AT1G08860
See related: Araport:AT1G08860
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: BONZAI 3; F7G19.25; F7G19_25
Summary: Encodes a copine-like protein, which is a member of a newly identified class of calcium-dependent, phospholipid binding proteins that are present in a wide range of organisms. Overexpression of this gene suppresses bon1-1 phenotypes. Double mutant analyses with bon1-1 suggest that BON1 and BON3 have overlapping functions in maintaining cellular homeostasis and inhibiting cell death.
