QA-Y — Aspergillus nidulans FGSC A4

Summary

ANIA_07667 (QA-Y) in Aspergillus nidulans FGSC A4 encodes a major facilitator superfamily (MFS) sugar transporter with proton:sugar symporter activity, localised to the plasma membrane. This gene is associated with monocarboxylic acid metabolism and carbohydrate transport. Studies of related genes in other species link the QA-Y family to quinate permease and MFS sugar transporters, though this specific function is not yet established in A. nidulans. The gene is located on chromosome 4 and has multiple synonyms including HGT14, QUTD, and ASD-3, reflecting its membership in the fungal sugar transporter family.
