MALT1(redirected from mucosa-associated lymphoid tissue lymphoma translocation protein 1)
MALT1A gene on chromosome 18q21 that encodes a protein which enhances BCL10-induced activation of NF-kappaB and is involved in nuclear export of BCL10. MALT1 binds to TRAF6, inducing TRAF6 oligomerisation and activation of its ubiquitin ligase activity; MALT1-dependent BCL10 cleavage plays an important role in T-cell antigen receptor-induced integrin adhesion.
MALT1 translocation t(11;18)(q21;q21) with BIRC2 occurs in ± 50% of cytogenetically abnormal low-grade MALT lymphomas.
