turnover of both Hxt3 and Hxt7 is dependent on the essential E3 ubiquitin ligase, Rsp5, indicating that the role of the Vid30c might be indirect of Hxt ubiquitylation
Title: Regulation of Hxt3 and Hxt7 turnover converges on the Vid30 complex and requires inactivation of the Ras/cAMP/PKA pathway in Saccharomyces cerevisiae.
The amino acid side chain length in transmembrane segment 5 of HXT7 is important for glucose affinity.
Title: Crucial effects of amino acid side chain length in transmembrane segment 5 on substrate affinity in yeast glucose transporter Hxt7.
Variation in the copy number of HXT6/HTX7 locus was observed in a survey of ~70 yeast strains.
Title: Reciprocal sign epistasis between frequently experimentally evolved adaptive mutations causes a rugged fitness landscape.
Saccharomyces cerevisiae was engineered for enhanced arsenite accumulation by overexpression of transporters responsible for the influx of the contaminant. The transporter genes FPS1 and HXT7 were cloned under the control of the late-phase ADH2-promoter.

Preferred Names: hexose transporter HXT7

NP_010629.3

High-affinity glucose transporter; member of the major facilitator superfamily, nearly identical to Hxt6p, expressed at high basal levels relative to other HXTs, expression repressed by high glucose levels; HXT7 has a paralog, HXT4, that arose from the whole genome duplication
