== Disease ==
[[http://www.uniprot.org/uniprot/ST14_HUMAN ST14_HUMAN]] Defects in ST14 are a cause of ichthyosis autosomal recessive with hypotrichosis (ARIH) [MIM:[http://omim.org/entry/610765 610765]]. ARIH is a skin disorder characterized by congenital ichthyosis associated with the presence of less than the normal amount of hair.<ref>PMID:17273967</ref>  
== Function ==
[[http://www.uniprot.org/uniprot/ST14_HUMAN ST14_HUMAN]] Degrades extracellular matrix. Proposed to play a role in breast cancer invasion and metastasis. Exhibits trypsin-like activity as defined by cleavage of synthetic substrates with Arg or Lys as the P1 site.

== Publication Abstract from PubMed ==
Iron overload disorders are characterized by the body's inability to regulate iron absorption and its storage which can lead to organ failures. Accumulated evidence has revealed that hepcidin, the master regulator of iron homeostasis, is negatively modulated by TMPRSS6 (matriptase-2), a liver-specific type II transmembrane serine protease (TTSP). Here, we report that treatment with a peptidomimetic inhibitor affecting TMPRSS6 activity increases hepcidin production in hepatic cells. Moreover, similar effects were observed when using non-peptidic inhibitors obtained through optimization of hits from high-throughput screening. Using HepG2 cells and human primary hepatocytes, we show that TMPRSS6 inhibitors block TMPRSS6-dependent hemojuvelin cleavage and increase HAMP expression and levels of secreted hepcidin.
