A cDNA clone encoding a novel zinc finger protein expressed in lymphoid
cells has been isolated. This protein contains 5 repeats of the C2H2 motif
previously described in the Drosophila gap gene, Kruppel, which is involved
in embryo segmentation. Northern blot analysis showed that the messenger
RNA (mRNA) encoding this protein is expressed at high levels in a variety
of T-leukemia cell lines, at lower levels in some B cells, but is not
observed in nonlymphoid cells. Within the T lineage, the mRNA is found at
high levels in both alpha beta and gamma delta T cells. These data suggest
that this cDNA, designated Hkr-T1, represents a gene that may contribute to
the determination of the differentiation and the specificity within
lymphoid cells.
