Description
centromere to telomere orientation; 10 exons; large 5 untranslated region, start codon in exon 3, stop codon in exon 10.
Transcription
6.5 kb mRNA
Proteins

BIRC3 protein - Mathijs Baens, Peter Marynen
Description
68 kDa; 604 amino acids. The protein contains three baculovirus inhibition of apoptosis (BIR) repeats, a caspace recruitment domain or CARD and a carboxyterminal Zn-binding RING domain.
Expression
wide, most abundantly in kidney, liver, small intestine and lung
Function
Member of the inhibitor of apoptosis (IAP) protein family. Binds to the tumor necrosis factor receptor via its associated factors TRAF1 and TRAF2 and inhibits apoptosis, probably by interfering with activation of caspaces.
Homology
with Baculovirus IAP proteins, Drosophila DIAP1 and DIAP2
Implicated in
Entity name
Disease
B-cell non Hodgkin lymphoma (NHL); marginal zone B-cell lymphoma (MZBCL) of mucosa-associated lymphoid tissue (MALT); found in extranodal MZBCL or MALT-type, absent in splenic and nodal MZBCL
Prognosis
For gastric MALT-type lymphomas, t(11;18) is a clonal marker for resistance to Helicobacter pylori eradication therapy and antigen independent growth
Cytogenetics
t(11;18) is frequently associated with deletions affecting 3 API2 on chromosome 11 or 5 MALT1 on chromosome 18.
Hybrid gene
5 API2 on chromosome 11q21 translocated on chromosome 18 in frame with 3 MALT1. Deletions often exclude the expression of the reciprocal 5 MLT API2 3 transcript.
Fusion protein
All MALT-type lymphomas reported with a t(11;18) express an in frame API2-MLT fusion protein with consistently the three BIR domains of API2 fused to the caspace p20 domain and VDJ4-like domain of MLT.

BIRC3/MALT1 fusion protein - Mathijs Baens, Peter Marynen
Oncogenesis
Transient expression of the API2-MLT fusion protein acitvates an NF-KB luciferase reporter construct, suggesting the involvement of this signaling cascade in MALT lymphomagenesis
