LocalizationUniProt · AlphaFold · HPA

Whether an antibody against LINC00242 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 reachability: Unknown
Secreted: No
Transmembrane segments: 0
Mean surface accessibility (rSASA): 0.74

Cancer expressionTCGA

Across TCGA tumor cohorts, this protein is over-expressed in roughly 4% of surveyed tumor types (aggregate summary; per-cohort expression, alteration, and survival load in the interactive view).

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads LINC00242 as an antibody target. Whether an autoantibody or antibody against LINC00242 could matter depends on whether native LINC00242 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

LINC00242 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 LINC00242 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
