Organism: Homo sapiens
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Also known as: KLKL3; KLK-L3
Summary: The protein encoded by this gene is a kallikrein-related serine protease. This gene is activated by steroid hormones in a human breast cancer cell line, making it a good marker for cancer detection. The encoded protein is found primarily in the cytoplasm.[provided by RefSeq, Oct 2010]
Annotation information: Note: The KLK9 gene is immediately upstream of the KLK8 gene. There are a few transcripts (DQ267419, DQ267420, AY566267, and BC040887) that span the gap between these two genes and which suggest the presence of a bicistronic transcript. However, there is no published support for that, so they will continue to be represented as separate genes. [13 Feb 2013]

What's a GeneRIF?

Pronounced correlations between KLK10/KLK11 (rs = 0.647) and between KLK9/KLK15 (rs = 0.716) mRNA, but not between other combinations, indicate coordinate expression of distinct pairs of peptidases
Title: Clinical relevance of kallikrein-related peptidase 9, 10, 11, and 15 mRNA expression in advanced high-grade serous ovarian cancer.
Data suggest that mature KLK9 (kallikrein 9) is a glycosylated chymotrypsin-like enzyme with strong preference for tyrosine over phenylalanine at P1 cleavage position; substrate specificity of KLK9 appears to extend to KLK10 and midkine; enzyme activity is enhanced by Mg2+ and Ca2+, but is reversibly attenuated by Zn2+; KLK9 is inhibited in vitro by many naturally occurring or synthetic protease inhibitors.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
