MALT1/Paracaspase (MALT1) was independently identified as a member of the human paracaspase family and an interacting partner of B-cell lymphoma. Human MALT1has two isoforms, isoform a is an amino acid protein of 824 amino acids, and human MALT1 isoform b is an amino acid protein of 813 amino acids. MALT1 is a caspase-like protein that contains an N-terminal death domain, two Ig-like domains, and a C-terminal caspase-like domain. It binds to Bcl10 through its Ig-like domains and cooperates with Bcl10 to activate NF-kappaB. MALT1 is thought to play an important role in NF-kappaB signaling by enchancing NF-kappaB activation through interaction with Bcl10. Interaction between MALT1 and Bcl10 mediates IKK activation in vitro through facilitatiing the ubiquitination of NEMO by the ubiquitin-conjugating enzyme UBC13. Four recurrent chromosomal translocations have been described in non-Hodgkin B-cell lymphoma of the mucosa-associated lymphoid issue (MALT) type. Translocations involving Bcl10 and MALT1 may lead to elevated NF-kappaB activity in MALT B-cell lymphoma. Two alternatively spliced transcript variants encoding different isoforms and have been described for the MALT1 gene
