Function
GGT2 may be essential for glutathione transport into developing seeds.

Protein Families
Gamma-glutamyltransferase family
Subcellular Location
Secreted, extracellular space, apoplast. Note=Associated with the plasma membrane and cell wall.
Tissue Specificity
Expressed in roots, immature trichomes and pollen. In developing siliques, specifically expressed in the embryo, endosperm, outer integument and a small portion of the funiculus.
