[A zinc-binding non-metallothionein protein isolated from normal and regenerating liver].

A zinc-binding nonmetallothionein protein has been isolated from cytosol of normal and regenerating liver. It is a dimer with molecular weight of ca. 20 kDa and contains one zinc ion. Zinc-dependent monomer in equilibrium dimer transition was observed. The role of the protein in regulation of intracellular content of zinc ions has been discussed.
