Description
Matriptase-2 (Tmprss6), a recently described member of the TTSP family, is an essential regulator of iron homeostasis. Tmprss6-/- mice display an overt phenotype of alopecia and a severe iron deficiency anemia. These hematological alterations found in Tmprss6-/- mice are accompanied by a marked up-regulation of hepcidin, a negative regulator of iron export into plasma.
