Transmembrane protease, serine 4 is a protein in humans that is encoded by the TMPRSS4 gene. [1]
This gene encodes a member of the serine protease family. Serine proteases are known to be involved in a variety of biological processes, whose malfunction often leads to human diseases and disorders. This gene was identified as a gene overexpressed in pancreatic carcinoma. The encoded protein is membrane bound with a N-terminal anchor sequence and a glycosylated extracellular region containing the serine protease domain. Multiple transcript variants encoding different isoforms have been found for this gene.
Chromosome 2 is one of the twenty-three pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 2 is the second-largest human chromosome, spanning more than 242 million base pairs and representing almost eight percent of the total DNA in human cells.
Chromosome 3 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 3 spans 201 million base pairs and represents about 6.5 percent of the total DNA in cells.
Chromosome 4 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 4 spans more than 193 million base pairs and represents between 6 and 6.5 percent of the total DNA in cells.
Chromosome 11 is one of the 23 pairs of chromosomes in humans. Humans normally have two copies of this chromosome. Chromosome 11 spans about 135 million base pairs and represents between 4 and 4.5 percent of the total DNA in cells. The shorter arm is termed 11p while the longer arm is 11q. At about 21.5 genes per megabase, chromosome 11 is one of the most gene-rich, and disease-rich, chromosomes in the human genome.
Neutrophil elastase is a serine proteinase in the same family as chymotrypsin and has broad substrate specificity. Neutrophil elastase is secreted by neutrophils during inflammation, and destroys bacteria and host tissue. It also localizes to neutrophil extracellular traps (NETs), via its high affinity for DNA, an unusual property for serine proteases.
Kallikrein-5, formerly known as stratum corneum tryptic enzyme (SCTE), is a serine protease expressed in the epidermis. In humans it is encoded by the KLK5 gene. This gene is one of the fifteen kallikrein subfamily members located in a cluster on chromosome 19. Its expression is up-regulated by estrogens and progestins. Alternative splicing results in multiple transcript variants encoding the same protein.
Kunitz-type protease inhibitor 1 is an enzyme that in humans is encoded by the SPINT1 gene.
Kallikrein-11 is a protein that in humans is encoded by the KLK11 gene.
Transmembrane protease, serine 3 is an enzyme that in humans is encoded by the TMPRSS3 gene.
Transmembrane protease, serine 2 is an enzyme that in humans is encoded by the TMPRSS2 gene. It belongs to the TMPRSS family of proteins, whose members are transmembrane proteins which have a serine protease activity. These proteins often consist of an N-terminal intracellular domain, a C-terminal protease domain, a transmembrane domain and a variable extracellular stem region that constitutes the characterization of the protein. The TMPRSS2 protein is found in high concentration in the cell membranes of epithelial cells of the lung and of the prostate, but also in the heart, liver and gastrointestinal tract.
Kallikrein-8 is a protein that in humans is encoded by the KLK8 gene.
Serine protease 23 is an enzyme that in humans is encoded by the PRSS23 gene.
Kallikrein-12 is a protein that in humans is encoded by the KLK12 gene.
Transmembrane protease, serine 11D is an enzyme that in humans is encoded by the TMPRSS11D gene.
Transmembrane protease, serine 6 is an enzyme that in humans is encoded by the TMPRSS6 gene.
Brain-specific serine protease 4 (BSSP-4), also known as serine protease 22 or tryptase epsilon, is an enzyme that in humans is encoded by the PRSS22 gene.
Rhomboid-related protein 2 is a protein that in humans is encoded by the RHBDL2 gene.
Transmembrane protease, serine 11B is a protein that in humans is encoded by the TMPRSS11B gene.
Transmembrane serine protease 11F is a protein that in humans is encoded by the TMPRSS11F gene.
Transmembrane serine protease 7 is a protein that in humans is encoded by the TMPRSS7 gene.
