We have shown previously that chromosomal translocations involving chromosome 3q27 and immunoglobulin gene regions are the third most common specific translocations in non-Hodgkin's lymphoma (NHL). We now report the isolation of a gene that is disrupted in two cases by t(3;14) and t(3;4) translocations. The gene (LAZ3) encodes a 79 kDa protein containing six zinc-finger motifs and sharing amino-terminal homology with several transcription factors including the Drosophila tramtrack and Broad-complex genes, both of which are developmental transcription regulators. LAZ3 is transcribed as a 3.8 kb message predominantly in normal adult skeletal muscle and in several NHL carrying 3q27 chromosomal defects. We suggest that it may act as a transcription regulator and play an important role in lymphomagenesis.
