NCBI Protein Information
Endonuclease/exonuclease/phosphatase family protein
NCBI Summary
Encodes an inositol polyphosphate 5-phosphatase with phosphatase activity toward only Ins(1,4,5)P3. Induced in response to ABA and wounding treatments. Expressed in young seedlings and flowers, while no transcripts were detectable in maturated roots, stems, and rosette leaves Modulates the development of cotyledon veins through its regulation of auxin homeostasis. Involved in blue light light#Aeistimulated increase in cytosolic calcium ion.

UniProt Comments
Converts inositol 1,4,5-trisphosphate (Ins(1,4,5)P3) to inositol 1,4-bisphosphate. Modulates cotyledon vein development through regulating auxin homeostasis. Involved in blue light responses. Decreases the amount of KIN10 degraded by the proteasome under low nutrient conditions. Participates with IP5P12 in the control of Ins(1,4,5)P3/Ca2+ levels that is crucial for maintaining pollen dormancy and regulating early germination of pollen. May modulate auxin transport by regulating vesicle trafficking and thereby plays a role in root gravitropism.
