OverviewNCBI Gene

This gene encodes a protein containing an RNA-binding motif in the N-terminus and four SRGY (serine, arginine, glycine, tyrosine) boxes in the C-terminus. This protein likely functions as a splicing factor during spermatogenesis. Multiple closely related paralogs of this gene are found in a gene cluster in the AZFb azoospermia factor region of chromosome Y. Most of these related copies are thought to be pseudogenes, though several likely encode functional proteins. [provided by RefSeq, Mar 2016]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against RBMY1A1 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 RBMY1A1 as an antibody target. Whether an autoantibody or antibody against RBMY1A1 could matter depends on whether native RBMY1A1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

RBMY1A1 is annotated as predominantly intracellular. Intracellular proteins are common autoantibody markers, becoming visible to the immune system after cell injury or altered processing, but are usually markers of disease rather than direct drivers.

Annotation status

The present source text does not explicitly label RBMY1A1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
