Disease

[MALT1_HUMAN] Note=A chromosomal aberration involving MALT1 is recurrent in low-grade mucosa-associated lymphoid tissue (MALT lymphoma). Translocation t(11;18)(q21;q21) with BIRC2. This translocation is found in approximately 50% of cytogenetically abnormal low-grade MALT lymphoma.

Function

[MALT1_HUMAN] Enhances BCL10-induced activation of NF-kappa-B. Involved in nuclear export of BCL10. Binds to TRAF6, inducing TRAF6 oligomerization and activation of its ligase activity. Has ubiquitin ligase activity. MALT1-dependent BCL10 cleavage plays an important role in T-cell antigen receptor-induced integrin adhesion.^[1] ^[2] ^[3]

Publication Abstract from PubMed

The formation of the CBM (CARD11-BCL10-MALT1) complex is pivotal for antigen-receptor-mediated activation of the transcription factor NF-kappaB. Signaling is dependent on MALT1 (mucosa-associated lymphoid tissue lymphoma translocation protein 1), which not only acts as a scaffolding protein but also possesses proteolytic activity mediated by its caspase-like domain. It remained unclear how the CBM activates MALT1. Here, we provide biochemical and structural evidence that MALT1 activation is dependent on its dimerization and show that mutations at the dimer interface abrogate activity in cells. The unliganded protease presents itself in a dimeric yet inactive state and undergoes substantial conformational changes upon substrate binding. These structural changes also affect the conformation of the C-terminal Ig-like domain, a domain that is required for MALT1 activity. Binding to the active site is coupled to a relative movement of caspase and Ig-like domains. MALT1 binding partners thus may have the potential of tuning MALT1 protease activity without binding directly to the caspase domain.
