OverviewNCBI Gene

This gene encodes a member of the TALE/TGIF homeobox family of transcription factors. Testis-specific expression suggests that this gene may play a role in spermatogenesis. A homolog of this gene lies within the male specific region of chromosome Y, in a block of sequence that is thought to be the result of a large X-to-Y transposition. [provided by RefSeq, Jul 2008]

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads TGIF2LX as an antibody target. Whether an autoantibody or antibody against TGIF2LX could matter depends on whether native TGIF2LX is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

TGIF2LX is annotated as predominantly intracellular. Intracellular proteins are common autoantibody markers, becoming visible to the immune system after cell injury or altered processing, but are usually markers of disease rather than direct drivers.

Annotation status

The present source text does not explicitly label TGIF2LX as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
