Abstract

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.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
