OverviewNCBI Gene

This gene encodes a transmembrane protein component of a mechanosensitve ion channel that is activated by mechanical stimuli in various cell types and confers slowly adapting, mechanically activated currents in dorsal root ganglion neurons. Mechanically activated ion channels are sensors that are critical for hearing, touch, pain, and blood pressure regulation. [provided by RefSeq, Jul 2017]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against TMEM150C 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 TMEM150C as an antibody target. Whether an autoantibody or antibody against TMEM150C could matter depends on whether native TMEM150C is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

TMEM150C is annotated at the cell surface, where native TMEM150C 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 TMEM150C as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
