A new 8.2-kDa protein factor was isolated from cell culture of a promyelocyte leukemic HL-60 cell line that exhibited a differentiation-inducing effect upon the initial cell line. The primary structure of this factor was determined by sequencing the protein (N-terminal region) and the corresponding cDNA. A molecule of the differentiation factor secreted by HL-60 cells consisted of 54 amino acid residues and was glycosylated.
