Rabbit polyclonal to MALT1MALT1 was independently identified as a member of the human paracaspase family and an interacting partner of B cell lymphoma. Two alternatively spliced transcript variants encoding different isoforms (a and b) have been described for the MALT1 gene.Human MALT isoform a is an amino acid protein of 824 amino acids, and human MALT2 isoform b is an amino acid protein of 813 amino acids. MALT1 is thought to play a role in NFkappaB 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. Two of them, t(14;18)(q32;q21) and t(11;18)(q21;q21), are found in 30% to 50% of extranodal MALT lymphomas. The first translocation juxtaposes the MALT1 gene to the IgH promoter region, resulting in the deregulation of MALT1 expression, whereas the second translocation generates a fusion between MALT1 and the inhibitor of apoptosis gene API2 (cIAP2/HIAP1). The other two much rarer translocations, t(1;14)(p22;q32)and t(1;2)(p22;p12), target Bcl10 gene on the short arm of chromosome 1. Translocations involving Bcl10 and Malt1 may lead to elevated NFkappaB activity in MALT B cell lymphoma.
