Analyses of the human PAX-5 locus and of the 5' region of the mouse Pax-5 gene revealed that transcription from two distinct promoters results in splicing of two alternative 5' exons to the common coding sequences of exons 2-10. Transcription from the upstream promoter initiates downstream of a TATA box and occurs predominantly in B-lymphocytes, whereas the TATA-less downstream promoter is active in all Pax-5-expressing tissues. The human PAX-5 gene is located on chromosome 9 in region p13, which is involved in t(9;14)(pl3;q32) translocations recurring in small lymphocytic lymphomas of the plasmacytoid subtype and in derived large-cell lymphomas. A previous molecular analysis of a t(9;14) breakpoint from a diffuse large-cell lymphoma (KIS-1) demonstrated that the immunoglobulin heavy-chain (IgH) locus on 14q32 was juxtaposed to chromosome 9p13 sequences of unknown function [Ohno, H., Furukawa, T., Fukuhara, S., Zong, S. Q., Kamesaki, H., Shows, T. B., Le Beau, M. M., McKeithan, T. W., Kawakami, T. &amp; Honjo, T. (1990) Proc. Natl. Acad. Sci. USA 87,628-632]. Here we show that the KIS-1 translocation breakpoint is located 1807 base pairs upstream of exon 1A of PAX-5, thus bringing the potent Emu enhancer of the IgH gene into close proximity of the PAX-5 promoters. These data suggest that deregulation of PAX-5 gene transcription by the t(9;14)(pl3;q32) translocation contributes to the pathogenesis of small lymphocytic lymphomas with plasmacytoid differentiation.
