The isolation of cDNA clones for CD48.
HuLy-m3 is an Mr 47,000 pan-leukocyte antigen detected by the monoclonal antibody (mAb) 5-4.8. This report describes the isolation and analysis of a cDNA clone encoding HuLy-m3. Serological analysis demonstrated that antibodies of the CD48 cluster also reacted with transfected cells expressing HuLy-m3. The DNA sequence of the clone suggests linkage to the cell membrane through a glycosyl phosphatidylinositol tail and this was verified experimentally. Sequence similarity with the human B-cell activation antigen Blast-1 was noted.
