APS1 — Brassica juncea

Summary

BJUB02G50900S (APS1) on chromosome B02 of Indian mustard (Brassica juncea) encodes a protein with acid phosphatase activity, nutrient reservoir activity, protein binding, and autophagy adaptor activity. The protein belongs to the APS1/VSP family and contains HAD-like and acid phosphatase domains. 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. Studies of related genes in other species connect the family to starvation response.
