| DNA/RNA |
| Transcription | different splicings (and different names for the gene) |
| Protein |
| Description | 387 (ABI1) to 508 (e3B1) amino acids; 43 to 72 kDa; NH2- an homeodomain homologous region and a SH3 domain -COOH |
| Expression | wide, in adults and in the embryo |
| Localisation | cytosol |
| Function | cell growth inhibitor; interacts withENL, another fusion partner of MLL, by binding it through its SH3 domain; the mouse Abi-1 protein is an AB-binding protein that suppresses v-ABL transforming activity |
| Implicated in |
| Entity | t(10;11)(p11.2;q23) acute non lymphoblastic leukemia (ANLL) --> MLL- ABI1 |
| Note | only one case to date |
| Disease | M4 ANLL in an infant |
| Oncogenesis | MLL-ABI1 displays a transcriptional transactivator activity similar to MLL-ENL; they may act in a common oncogenic pathway |
