APS1 — Brassica juncea

Summary

BJUB04G39330S (APS1) in Indian mustard (Brassica juncea) on chromosome B04 encodes a protein with acid phosphatase activity, autophagy adaptor activity, nutrient reservoir activity, and protein binding, belonging to the APS1/VSP and HAD-like superfamilies. It is associated with glutathione anabolism, sulfur metabolism, defense response, and protein targeting to the vacuole involved in autophagy. The gene product localizes to the plant-type vacuole, plastid, endoplasmic reticulum, nucleus, plasmodesma, and extracellular space. APS1 is linked to thermotolerance and is related to the ATG8-interacting protein ATI2. Related genes in other species link the family to starvation response, acid phosphatase (EC 3.1.3.2) activity, and callus induction.
