fetiun-like protein
-
the enzyme circulates in the blood stream in complex with a specific protein inhibitor, formerly termed nephrosin inhibitor, which is a homologue of fetuin, a large plasma protein with many functions. Fish fetuin, like its mammalian counterpart fetuin A, contains cystatin-like domains and is related to cystatin C-like inhibitors of cysteine cathepsins
