OverviewNCBI Gene

The protein encoded by this gene is a cytokine that controls the production, differentiation, and function of macrophages. The active form of the protein is found extracellularly as a disulfide-linked homodimer, and is thought to be produced by proteolytic cleavage of membrane-bound precursors. The encoded protein may be involved in development of the placenta. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2011]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against CSF1 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 CSF1 as an antibody target. Whether an autoantibody or antibody against CSF1 could matter depends on whether native CSF1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

CSF1 is annotated at the cell surface, where native CSF1 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 CSF1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
