Protein attributes

Sequence length	570 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Low-affinity glucose transporter. HXT1 is as well involved in the transport of mannose.
Subcellular location	Membrane; Multi-pass membrane protein.
Developmental stage	Expression is maximal during lag and early exponential phases of growth, decreasing upon further entry into exponential growth.
Induction	Repressed at high glucose concentrations.
Miscellaneous	Glucose transport is thought to be mediated by two kinetically distinct systems, a glucose-repressible high-affinity system and a constitutive low-affinity system. Present with 23300 molecules/cell in log phase SD medium. Ref.5
Sequence similarities	Belongs to the major facilitator superfamily. Sugar transporter (TC 2.A.1.1) family. [View classification]
