QA-Y — Aspergillus nidulans FGSC A4

Summary

ANIA_05551 (QA-Y, AnQA-Y) on Aspergillus nidulans chromosome 5 encodes a major facilitator superfamily (MFS) sugar transporter with proton:sugar symporter activity. The gene product is associated with monocarboxylic acid metabolism and carbohydrate transport, and localises to the plasma membrane. Studies of related genes in other species link the family to quinate permease function and broader MFS sugar transport, though these roles are not established for this specific gene.
