APS1 — Brassica juncea

Summary

BJUB04G43190S (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 acid phosphatase and HAD-like superfamily domains. The gene is associated with glutathione anabolism, sulfur metabolism, protein targeting to the vacuole involved in autophagy, and defense response. It localizes to multiple cellular compartments including the plastid, endoplasmic reticulum, nucleus, plant-type vacuole, plasmodesma, and extracellular space. APS1 is associated with thermotolerance and is related to the ATG8-interacting protein ATI2. Related genes in other species connect it to starvation response, while sequence similarity links the family to acid phosphatase activity (EC 3.1.3.2) and callus induction traits.
