APS1 — Brassica juncea

Summary

BJUA06G01460S (APS1) in Indian mustard (Brassica juncea) on chromosome A06 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. This gene is associated with glutathione anabolism, sulfur metabolism, defense response, and protein targeting to the vacuole involved in autophagy. It is linked to thermotolerance and is connected to the ATG8-interacting protein ATI2. The encoded product localizes to multiple cellular compartments including the plant-type vacuole, plastid, endoplasmic reticulum, nucleus, plasmodesma, and extracellular space. Related genes in other species link the APS1 family to starvation response and callus induction.
