The myeloid integrin CD11b is expressed selectively on the surface of mature monocytes, macrophages, granulocytes, and natural killer cells. Tissue-specific and developmentally regulated expression of CD11b is controlled at the level of mRNA transcription, and recent characterization of the human CD11b promoter indicates that the first 92 bp of 5'-flanking DNA are sufficient to direct tissue-specific expression of a reporter gene. Here we show that the sequence AAAAGGAGAAG at base pair -20 of the CD11b promoter binds the proto-oncogene PU.1 in vitro and that mutation of this site significantly reduces the ability of the CD11b promoter to direct expression of a reporter gene in myeloid cells but not in nonmyeloid cells. PU.1 may thus represent a major determinant of the myeloid expression of CD11b.
