Isolation of a cDNA encoding the human CD38 (T10) molecule, a cell surface glycoprotein with an unusual discontinuous pattern of expression during lymphocyte differentiation.

Abstract

A cDNA clone encoding the human lymphocyte differentiation Ag CD38 was isolated from a mixture of four different lymphocyte CDNA libraries expressed transiently in COS cells and screened by panning with mAb. Transfected COS cells expressed a surface protein of Mr 46,000 that was similar to the native CD38 molecule expressed on the B cell line Daudi and the T cell leukemia HPB-ALL and which was recognized by each of the CD38 specific mAb HIT-2, T16, T168, HB7, 5D2, ICO-18, and ICO-20. The CD38 cDNA sequence predicts an unusual 30-kDa polypeptide with a short N-terminal cytoplasmic tail, and a carboxyl-terminal extracellular domain carrying the four potential N-linked glycosylation sites. The absence of significant homology with other known surface Ag including members of the Ig superfamily ruled out the possibility that CD38 was the human homologue of the murine Qa2 molecule as has been suggested previously. PvuII digests of human genomic DNA revealed a polymorphism linked to the CD38 gene.

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.
