    Summary
    Kallikreins are a subgroup of serine proteases having diverse physiological functions. Growing evidence suggests that many kallikreins are implicated in carcinogenesis and some have potential as novel cancer and other disease biomarkers. This gene is one of the fifteen kallikrein subfamily members located in tandem in a gene cluster on chromosome 19. The encoded protein may be involved in proteolytic cascade in the skin and may serve as a biomarker for ovarian cancer. Alternate splicing of this gene results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2013]
    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]

    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.

      Description
      Transcript Variant: This variant (4, also known as T4) lacks three exons in the coding region, which results in a frameshift and an early stop codon, compared to variant 2. The encoded isoform (4) is shorter and has a distinct C-terminus, compared to isoform 2. This variant is based on data in PMID: 11309326 and 20360129.

      Status: REVIEWED

      Description
      Transcript Variant: This variant (6, also known as T6) lacks an alternate internal exon, compared to variant 2. This variant is represented as non-coding because the use of the 5'-most expected translational start codon, as used in variant 2, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD). This variant is based on data in PMID: 20360129.
