OverviewNCBI Gene

The protein encoded by this gene is an adaptor protein which contains five LIM domains, or double zinc fingers. The protein is likely involved in integrin signaling through its LIM domain-mediated interaction with integrin-linked kinase, found in focal adhesion plaques. It is also thought to act as a bridge linking integrin-linked kinase to NCK adaptor protein 2, which is involved in growth factor receptor kinase signaling pathways. Its localization to the periphery of spreading cells also suggests that this protein may play a role in integrin-mediated cell adhesion or spreading. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2010]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against LIMS1 can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Genetic constraint and essentialitygnomAD · DepMap

Does the body need this protein intact? Low LOEUF or a strong DepMap dependency means loss or blockade of the protein is likely to be felt.

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads LIMS1 as an antibody target. Whether an autoantibody or antibody against LIMS1 could matter depends on whether native LIMS1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

LIMS1 is annotated at the cell surface, where native LIMS1 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 LIMS1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
