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

Proteins

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

Implicated in

Entity name
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 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
Fusion 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
