摘要
The MLL gene, the closest human homologue to the Drosophila trithorax gene, undergoes chromosomal translocation with a large number of different partner genes in both acute lymphoid and acute myeloid leukemias, We have identified a new partner gene, EEN, fused to MLL in a case of acute myeloid leukemia, The gene is located on chromosome 19p13, where two other MLL partner genes, ENL and ELL/MEN have also been identified, The deduced protein of 368 aa contains a central cy-helical region and a C-terminal Src homology 3 (SH3) domain most similar to the C-terminal SH3 domain found in the Grb2/Sem-5/Drk family of genes, Sequence analysis of the fusion MLL/EEN transcript in our patient reveals that exon 6 of MLL is fused to the N-terminal end of EEN, a fusion that would create a chimeric protein that includes the major functional domain of EEN, EEN is expressed in a variety of tissue types and encodes a protein of approximately 46 kDa, The EEN protein is the human homologue of a member of a recently described murine SH3 domain-containing protein family, It is also highly related to a putative gene identified in Caenorhabditis elegans, and a number of similar sequences are present in the EST databases of several species.
