OverviewNCBI Gene

This gene encodes an adaptor protein and member of a cytoplasmic protein family involved in cell migration. The encoded protein contains a putative Src homology 2 (SH2) domain and guanine nucleotide exchange factor-like domain which allows this signaling protein to form a complex with scaffolding protein Crk-associated substrate. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2011]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against SH2D3C 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 SH2D3C as an antibody target. Whether an autoantibody or antibody against SH2D3C could matter depends on whether native SH2D3C is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

SH2D3C is annotated at the cell surface, where native SH2D3C 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 SH2D3C as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
