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.
