Abstract: The present invention provides a human metallothionein (HMBP-I) and polynucleotides which identify and encode HMBP-I. The invention also provides genetically engineered expression vectors and host cells comprising the nucleic acid sequences encoding HMBP-I and a method for producing HMBP-I. The invention also provides for agonists, antibodies, or antagonists specifically binding HMBP-I, and their use, in the prevention and treatment of diseases associated with expression of HMBP-I. Additionally, the invention provides for the use of antisense molecules to polynucleotides encoding HMBP-I for the treatment of diseases associated with the expression of HMBP-I. The invention also provides diagnostic assays which utilize the polynucleotide, or fragments or the complement thereof, and antibodies specifically binding HMBP-I.
