OverviewNCBI Gene
This gene encodes an integral plasma membrane glycoprotein of the liver, islet beta cells, intestine, and kidney epithelium. The encoded protein mediates facilitated bidirectional glucose transport. Because of its low affinity for glucose, it has been suggested as a glucose sensor. Mutations in this gene are associated with susceptibility to diseases, including Fanconi-Bickel syndrome and noninsulin-dependent diabetes mellitus (NIDDM). Alternative splicing results in multiple transcript variants of this gene. [provided by RefSeq, Jul 2013]

Whether an antibody against SLC2A2 can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads SLC2A2 as an antibody target. Whether an autoantibody or antibody against SLC2A2 could matter depends on whether native SLC2A2 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
SLC2A2 is annotated at the cell surface, where native SLC2A2 is exposed to circulating antibodies and is a prime autoantibody target that could block, deplete, or overstimulate it.
Annotation status
The present source text does not explicitly label SLC2A2 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
