Full length cDNA clones encoding the mouse Fc gamma RI were isolated by using redundant oligonucleotide probes based on previously determined amino acid sequence of protein bound to an IgG2a antibody column. Sequence analysis of cDNA clones indicates that mouse Fc gamma RI is a transmembrane glycoprotein that is composed of three disulfide bonded extracellular Ig binding domains unlike Fc gamma RII of man and mouse. These extracellular domains contain five potential sites of N-linked glycosylation; three sites in the first domain and one in each of the second and third domains. In addition a transmembrane region is present followed by a cytoplasmic tail of 84 amino acids. Analysis of the amino acid sequence of the first two extracellular domains of Fc gamma RI indicate that these are highly homologous to the extracellular domains of Fc gamma RII; the third domain is different and shows a lower level of homology to other FcR domains but is clearly related to the Ig super-family. Transfected cells expressing Fc gamma RI were shown to bind immune complexes of rabbit IgG; and monomeric IgG2a bound to transiently transfected cells with an affinity of approximately 5 x 10(7) M-1, i.e. the receptor was of high affinity and therefore was by definition Fc gamma RI. Northern analysis demonstrated that Fc gamma RI mRNA could be detected in the Fc gamma RI+ myeloid cell lines WEH1 3B and J774. Finally, Southern analysis indicated that Fc gamma RI is likely to be encoded by a single copy gene of approximately 9 kb.
