DNA/RNA

Description 15 exons spanning 226 kb, with 3 non coding exons in 5'; 2 putative promoters
Transcription transcription of 4.5 and 4 kb RNA

Protein

Description 931 amino acids; contains in the NH2-term a SAF (scaffold attachment factor) box; SAF box bind the DNA minor grove; supposed to attach DNA to nuclear scaffold
Expression wide
Function may have a role in chromatin organization

Note
  
Entity t(1;22)(p13;q13) / acute megakaryocytic leukaemia (M7 AML) --> OTT -MAL
Disease acute megakaryocytic leukaemia found in infants
Prognosis complete remission in only 50% of cases; median survival: 8 months
Cytogenetics 60% of cases have the t(1;22) as a single anomaly; the remaining cases exhibit complex and hyperploid clones
Hybrid/Mutated Gene 5' OTT - 3' MAL, comprisng most of OTT fused to most of MAL; the reciprocal 5' MAL - 3' OTT may or may not be present
Abnormal Protein includes most of OTT with the RNA recognition motifs and the SPOC domain in N-term, and most of MAL, with the scaffold attachment factor box in C-term
Oncogenesis may play a role in chromatin organization, HOX differentiation pathways, or extracellular signaling
