OverviewNCBI Gene

This gene encodes a multi-domain protein that is a leucine-rich repeat kinase and a GDP/GTP binding protein. The encoded protein is thought to play a role in the regulation of bone mass. Mice lacking a similar gene showed severe osteopetrosis, increased bone mineralization and decreased bone resorption. [provided by RefSeq, Jan 2017]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against LRRK1 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 LRRK1 as an antibody target. Whether an autoantibody or antibody against LRRK1 could matter depends on whether native LRRK1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

LRRK1 is annotated at the cell surface, where native LRRK1 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 LRRK1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
