OverviewNCBI Gene

This gene encodes a 70kDa heat shock protein. In conjunction with other heat shock proteins, this protein stabilizes existing proteins against aggregation and mediates the folding of newly translated proteins in the cytosol and in organelles. The gene is located in the major histocompatibility complex class III region, in a cluster with two closely related genes which also encode isoforms of the 70kDa heat shock protein.

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against HSPA1L 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 HSPA1L as an antibody target. Whether an autoantibody or antibody against HSPA1L could matter depends on whether native HSPA1L is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

HSPA1L is annotated at the cell surface, where native HSPA1L 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 HSPA1L as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
