| DNA/RNA |
| Transcription | 5 kb mRNA; coding sequence: 1.7 kb |
| Protein |
| Description | 568 amino acids; 63 kDa; serine and proline rich in many places; possesses a nuclear targeting sequence |
| Localisation | nuclear |
| Function | transcription activator |
| Homology | with ENL (human) |

| Note | |
| Entity | t(9;11) (p22;q23)/AML -->KMT2A -MLLT3 |
| Disease | M5/M4 de novo and therapy related AML |
| Prognosis | the prognosis may not be as poor as in other 11q23 leukaemias in de novo cases; very poor prognosis in secondary AML cases |
| Cytogenetics | may be overlooked; often as a sole anomaly |
| Hybrid/Mutated Gene | variable breakpoints on both genes |
| Abnormal Protein | N-term -- AT hook and DNA methyltransferase from MLL fused to the 192 C-term amino acids from AF9 (as breakpoints are variable, this is only an exemple) |
