Human parotid secretory protein is an antibacterial in saliva and parotids
October 27th, 2003
Human parotid secretory protein is an antibacterial protein expressed in the salivary gland and saliva, which is related to mouse parotid secretory protein. According to a study from the United States, "Parotid secretory protein (PSP) is an abundant protein in mouse and rat parotid glands. A related sequence (C20orf70) was identified on human chromosome 20. The goal of this study was to determine if PSP is expressed in the human parotid gland. "The cDNA for human PSP was amplified from a human parotid cDNA sample. A peptide antibody, raised to the C-terminal peptide of PSP, identified the protein in human parotid tissue by immunofluorescence...
