MALT1

MALT1

A 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.

Molecular pathology
MALT1 translocation t(11;18)(q21;q21) with BIRC2 occurs in ± 50% of cytogenetically abnormal low-grade MALT lymphomas.

A pesar que esta plataforma molecular contiene la molecula adaptadora canonica ASC, la presencia de las proteinas MALT1 y Caspasa-8, aunado al hecho de que el mecanismo de activacion de este inflamasoma sea independiente de la internalizacion del patogeno, hacen que el mismo sea denominado "inflamasoma caspasa-8 no canonico" (78).

TCR stimulation induces the recruitment of A20 and the Bcl-10 adaptor protein into the MALT1 complex, leading to MALT1-mediated A20 processing.
Various known tumor-associated genes (bcl2, MALT1 and DCC at 18q21; and RAP1 at 4q21) and a gene related to the embryogenesis of gonads such as H-Y regulator gene at Xp22.3 are located at or near the translocation breakpoints.
