APS1 — Brassica juncea

Summary

BJUA08G16440S (APS1, also known as BjVSP3) encodes a protein belonging to the APS1/VSP family, which includes an acid phosphatase B-like domain and a HAD-like superfamily domain. The gene product exhibits acid phosphatase activity and nutrient reservoir activity. It is associated with glutathione anabolism, sulfur metabolism, and defense responses. The protein localizes to secretory vesicles, the plant-type vacuole, and the extracellular space. Related genes in other species link the family to phosphate starvation responses.
