TMPRSS11D Gene

What is the TMPRSS11D gene?

TMPRSS11D encodes transmembrane serine protease 11d (hat), a protein involved in airway epithelial serine protease. It belongs to the Antiviral category and is part of the Viral Defense & Interferon Response biological cluster. TMPRSS11D encodes human airway trypsin-like protease (HAT), expressed in the trachea and bronchi, which can activate respiratory viruses.

Biological role and pathway

TMPRSS11D is involved in the airway epithelial serine protease pathway, which plays a central role in regulating physiological processes relevant to immune defence, cellular energy, and systemic homeostasis. Genes within the Viral Defense & Interferon Response cluster work together to maintain balanced function across interconnected biological systems.

Variants in genes within this pathway may influence an individual's predisposition to altered function in these systems — particularly under conditions of physiological stress such as viral infection or prolonged illness.

Known genetic variants

The following variants (SNPs) in the TMPRSS11D gene have been studied in relation to antiviral and chronic illness. Each variant represents a single nucleotide position where individuals may carry different alleles.
