Entrez gene summary

This gene encodes a type II transmembrane serine protease. The encoded protein has an extracellular region that consists of two domains, a catalytic serine protease domain and a non-catalytic scavenger receptor cysteine-rich domain. This protein may be involved in diverse cellular functions including blood coagulation, maintenance of cell morphology and the growth and progression of certain cancers, particularly prostate cancer. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Apr 2009]

Staining summary

Moderate cytoplasmic staining was observed in the majority of normal cells. Hepatocytes, exocrine pancreas, gastric chief cells, large intestine and epididymis were strongly stained. Intercalated discs in heart muscle were distinctly stained. Lymphoid tissues were mainly weakly stained.
