Protein
Inositol-3-phosphate synthase isozyme 1
Organism
Arabidopsis thaliana
Function
Catalyzes the majority of myo-inositol synthesis required for plant growth and development. Acts as a repressor of programmed cell death and protects plant cells against cell death under high light intensity or long days. Controls its own transcription by inhibiting ATXR6 activity. Reduces the deposition of inhibitory histone marks on its own promoter.
Similarity
Belongs to the myo-inositol 1-phosphate synthase family.
