Description
The glandular kallikreins are a distinct group of serine proteases with molecular masses of 25,000 to 40,000. The glandular kallikrein gene family comprises 25 to 30 highly homologous genes that encode specific proteases involved in the processing of biologically active peptides (they cleave Met-Lys and Arg-Ser bonds in kininogen to release Lys-bradykinin). Several human kallikrein genes have been isolated.

Organ-Specific Notes

Human glandular kallikrein (hK2) has been shown to add important information regarding the early detection and staging of prostate cancer. Together with percent free PSA (%fPSA), hK2 may help to distinguish preoperatively between pT2 and pT3 prostate cancer.

Performance Comment

hK2, hK4 and hK11 do not distinguish cases from controls in these populations.
