General annotation (Comments)

Function

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. Ref.8 Ref.10 Ref.12

Subunit structure

Binds through its Ig-like domains to BCL10. Forms oligomers which bind to TRAF6. Ref.9

Subcellular location

Cytoplasmperinuclear region. Nucleus. Note: Shuttles between the nucleus and cytoplasm. Found in perinuclear structures together with BCL10. Ref.11

Tissue specificity

Highly expressed in peripheral blood mononuclear cells. Detected at lower levels in bone marrow, thymus and lymph node, and at very low levels in colon and lung.

Involvement in disease

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.

Sequence similarities

Belongs to the peptidase C14B family.

Contains 1 death domain.

Contains 2 Ig-like C2-type (immunoglobulin-like) domains.
