An individual clone, presumably carrying a 3 bp fragment of ceruloplasmin receptor cDNA was isolated from the expression library of human placenta cDNA using polyclonal specific antibodies to ceruloplasmin receptors. EcoR1-hydrolysate of isolated DNA was cloned in a pTZ19 bacterial vector and sequenced in the forward and reverse direction. The comparison of the revealed sequence with known sequences of human genome revealed its high similarity to ceruloplasmin cDNA.
