Note centromeric of ABL


Description 14 exons stretched over an area of about 84 kb. Exon 1, a noncoding exon, has (at least) three variants.
Transcription in a centromere to telomere direction 5192 bp mRNA; 2903 bp open reading frame.


Description The AF9q34 protein contains a GAP related domain (GRD), an 'FLR'-motif, a Pleckstrin homology (PH) domain and a calcium/phospho-lipid-binding C2/CALB domain; 967 amino acids.
Expression Expression in all human tissues with a relatively low level of expression in testis, placenta, spleen and peripheral blood leukocytes.
Function RasGAPs negatively regulate the activity of Ras proteins that modulate diverse cellular processes by cycling between the inactive GDP-bound and active GTP-bound state. DAB2 interacting protein.
Homology Homologous to human nGAP (or RAS protein activator like 2 (RASAL2)).

Implicated in

Entity t(9;11)(q34;q23) AML --> KMT2A- DAB2IP
Note Another t(9;11)(q34;q23) AML has been reported with involvement of MLL-FBP17.
Disease Only one case to date, a 62 yr old male patient with Acute Myeloid Leukemia (M5).
Cytogenetics The case was 46, XY, t(9;11)(q34;q23) and in 40% of the metaphases additional chromosomes 8 and 13 were observed.
Hybrid/Mutated Gene 5' MLL fused at exon 9 with the 3' end of AFq34.
Schematic representation of MLL, AF9q34, and the putative MLL-AF9q34 fusion protein.
Domains in MLL and AF9q34 are shaded: AT, AT-hook DNA binding motifs; SNL1 and SNL2, speckled nuclear localisation signals 1 and 2; CxxC, cysteine rich motif homologous to DNA methyltransferase (MT); PHD, plant homeodomain fingers; FYRN, FYRN domain; FYRC. FYRC domain; SET, SET domain; PH, Pleckstrin Homology Domain; GRD, GAP Related Domain. Arrows indicate the breakpoint (bp) sites in MLL and AF9q34.
Abnormal Protein The MLL-AF9q34 protein includes the entire GAP related domain (GRD) and the C2/CALB domain, but the PH domain is disrupted by the breakpoint in AF9q34.
