BCMP11 was homologous to hAG-2 (Genbank entry NM006408.2), an uncharacterised human protein encoded by a cDNA cloned from the MCF-7 breast cancer cell line (Thompson and Weigel, 1998) and localised to chromosomal band 7p21.3 (Petek et al, 2000). The gene discussed is AGR3; the disease is breast cancer.
