HGNC Approved Gene Symbol: CPO
Cytogenetic location: 2q33.3 Genomic coordinates (GRCh38): 2:206,939,518-206,969,474 (from NCBI)
By searching databases for sequences similar to CPA1 (114850) and CPB1 (114852), Wei et al. (2002) identified a partial CPO cDNA encoding a carboxypeptidase catalytic domain with all residues involved in zinc coordination and substrate catalysis. The predicted active site differs from that of other carboxypeptidases, and the enzyme likely cleaves C-terminal acidic amino acids.
By genomic sequence analysis, Wei et al. (2002) mapped the CPO gene to chromosome 2.
