Gene: Klk1c9 (kallikrein 1-related peptidase C9) Rattus norvegicus
No known orthologs.
Symbol: Klk1c9
Name: kallikrein 1-related peptidase C9
RGD ID: 727805
Description: Predicted to enable serine-type endopeptidase activity. Involved in positive regulation of vasoconstriction. Predicted to be active in secretory granule. Human ortholog(s) of this gene implicated in cardiomyopathy; chronic kidney disease; end stage renal disease; hypertension; and myocardial infarction. Orthologous to several human genes including KLK1 (kallikrein 1); INTERACTS WITH aristolochic acid; cyclosporin A; diuron.
Type: protein-coding
Previously known as: kallikrein a2; kallikrein, submaxillary gland S3; KLK-S3; Klk9; Klks3; Klna2; LOC292868; rGK-9; rK9; S3 kallikrein; SEV; submandibular enzymatic vasoconstrictor; submandibular glandular kallikrein-9; submaxillary gland S3 kallikrein; tissue kallikrein
