The human homolog of HAVcr-1 codes for a hepatitis A virus cellular receptor.

ABSTRACT: The hepatitis A virus cellular receptor 1 (HAVcr-1) cDNA was isolated from a cDNA expression library of African green monkey kidney (AGMK) cells by using protective monoclonal antibody (MAb) 190/4, which blocks the binding of hepatitis A virus (HAV) to AGMK cells. The HAVcr-1 cDNA codes for havcr-1, a 451-amino-acid class I integral-membrane mucin-like glycoprotein of unknown natural function. To determine the existence of a human homolog(s) of HAVcr-1 (huHAVcr-1), we used HAVcr-1-specific primers to amplify cDNAs from human liver and kidney mRNA by reverse transcription-PCR. Nucleotide sequence analysis revealed that the amplified liver and kidney huHAVcr-1 cDNAs were identical and that they coded for a 359-amino-acid glycoprotein, termed huhavcr-1, which was approximately 79% identical t
