Protein: Protein SABRE (Protein HYPERSENSITIVE TO PI STARVATION 4) (Q6IMT1)
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: May be involved in membrane trafficking (By similarity). Required for cell expansion, especially in root cortex, probably by counteracting the action of ethylene in promoting cells radial expansion. Involved in female organ development. Antagonistically interacts with ethylene signaling to regulate plant responses to Pi starvation.
Subcellular location: Secreted {ECO:0000250|UniProtKB:Q6IMT0}. Golgi apparatus {ECO:0000250|UniProtKB:K7VLR4}.
Interaction partners:
- Translation initiation factor IF-2
- Translation initiation factor IF-2
