Summary

GSDMC (gasdermin C, HGNC:7151) is a protein-coding gene on chromosome 8q24.21, encoding Gasdermin-C (Q9BYG8). This form constitutes the precursor of the pore-forming protein: upon cleavage, the released N-terminal moiety (Gasdermin-C, N-terminal) binds to membranes and forms pores, triggering pyroptosis.

Enables wide pore channel activity. Involved in pyroptotic inflammatory response. Located in cytoplasm. Is active in plasma membrane.

UniProt curated annotations — full annotation on UniProt →

Function. This form constitutes the precursor of the pore-forming protein: upon cleavage, the released N-terminal moiety (Gasdermin-C, N-terminal) binds to membranes and forms pores, triggering pyroptosis. Pore-forming protein that causes membrane permeabilization and pyroptosis. Produced by the cleavage of gasdermin-C by caspase CASP8 in response to death signals. After cleavage, moves to the plasma membrane where it strongly binds to membrane inner leaflet lipids. Homooligomerizes within the membrane and forms pores of 10-15 nanometers (nm) of inner diameter, triggering pyroptosis.

Subunit / interactions. Homooligomer; homooligomeric ring-shaped pore complex containing 27-28 subunits when inserted in the membrane.

Subcellular location. Cytoplasm. Cytosol Cell membrane.

Tissue specificity. Expressed mainly in trachea and spleen. In the esophagus, expressed in differentiating cells and probably in differentiated cells. Also detected in gastric epithelium.

Post-translational modifications. Cleavage by CASP8 relieves autoinhibition by releasing the N-terminal moiety (Gasdermin-C, N-terminal) that initiates pyroptosis. The cleavage site is unclear. According to a publication, it takes place after Asp-240 in response to alpha-ketoglutarate. Another paper reports cleavage by CASP8 after Asp-365. Palmitoylated.

Activity regulation. The full-length protein before cleavage is inactive: intramolecular interactions between N- and C-terminal domains mediate autoinhibition in the absence of activation signal. The intrinsic pyroptosis-inducing activity is carried by the released N-terminal moiety (Gasdermin-C, N-terminal) following cleavage by caspase CASP8.

Domain organisation. Intramolecular interactions between N- and C-terminal domains are important for autoinhibition in the absence of activation signal. The intrinsic pyroptosis-inducing activity is carried by the N-terminal domain.

Induction. Expression in induced by STAT3 and CD274/PD-L1 in response to hypoxia.

Similarity. Belongs to the gasdermin family.
