Rabbit anti-Human TMPRSS11D Polyclonal Antibody

Uniprot Id

O60235

Target Species

Human

Target Name

TMPRSS11D

Target Full Name

Transmembrane protease serine 11D

Target Function

May play some biological role in the host defense system on the mucous membrane independently of or in cooperation with other substances in airway mucous or bronchial secretions. Plays a role in the proteolytic processing of ACE2. Proteolytically cleaves and activates the human coronavirus 229E (HCoV-229E) spike glycoprotein which facilitate virus-cell membrane fusions; spike proteins are synthesized and maintained in precursor intermediate folding states and proteolysis permits the refolding and energy release required to create stable virus-cell linkages and membrane coalescence. Preferentially cleaves the C-terminal side of arginine residues at the P1 position of certain peptides, cleaving Boc-Phe-Ser-Arg-4-methylcoumaryl-7-amide most efficiently and having an optimum pH of 8.6 with this substrate.

Target Subcellular Location

Cell membrane; Single-pass type II membrane protein. Note=Activated by cleavage and secreted.; [Transmembrane protease serine 11D catalytic chain]: Secreted. Note=Activated by cleavage and secreted.

Target Protein Families

Peptidase S1 family

Target Tissue Specificity

Located in the cells of the submucosal serous glands of the bronchi and trachea.

Target Synonyms

TMPRSS11D; HAT; Transmembrane protease serine 11D; Airway trypsin-like protease

Target Background

This gene encodes a trypsin-like serine protease released from the submucosal serous glands onto mucous membrane. It is a type II integral membrane protein and has 29-38% identity in the sequence of the catalytic region with human hepsin, enteropeptidase, acrosin, and mast cell tryptase. The noncatalytic region has little similarity to other known proteins. This protein may play some biological role in the host defense system on the mucous membrane independently of or in cooperation with other substances in airway mucous or bronchial secretions. This protein facilitates entry of viruses into host cells by proteolytically cleaving and activating viral envelope glycoproteins.
