IP5 — Glycine max

Summary

GLYMA_04G030000V4 (GmIP5) encodes an inositol pentakisphosphate 2-kinase, an enzyme with inositol-1,4,5,6-tetrakisphosphate 2-kinase activity and inositol pentakisphosphate 2-kinase activity, and is associated with phytate biosynthesis. The gene is associated with phosphate homeostasis, sucrose metabolism, seed development, lateral root development, and responses to abiotic stresses including heat, cold, and osmotic stress. It has been linked to root hair elongation, phosphate sensing, and phytic acid content. The encoded protein localizes to the nucleus, cytosol, and nuclear envelope, and is also associated with mRNA binding, RNA helicase activity, and poly(A)+ mRNA nuclear export. Studies of related genes in other species link the family to seed phosphate and phytic acid content, arsenate tolerance, and defense responses.
