Biological Information

Background Information:

MALT1 (Mucosa-Associated Lymphoid Tissue Lymphoma Translocation Protein 1) is a cysteine protease that plays a crucial role in the activation of NF-κB signaling pathways, particularly in T and B lymphocytes. MALT1 functions as both a scaffold protein and a paracaspase, forming part of the CBM signalosome complex that is essential for lymphocyte activation and proliferation. MALT1 has been implicated in various lymphoid malignancies and has emerged as a potential therapeutic target for certain lymphomas and autoimmune disorders. However, the inhibition of MALT1 is associated with immunotoxicity, specifically affecting thymic Treg output and development.

Testing Information

Procedure Summary:

Human recombinant MALT1 expressed in HEK293 cells is used. Test compound and/or vehicle is preincubated with 2.82 μg/mL enzymeǂ in 1x MALT1 Assay Buffer of assay kit for 15 minutes at 37oC. The reaction is initiated by addition of 20 μM MALT1 substrate of assay kit for another 30-minute incubation period. Determination of the amount of MALT product formed is read spectrofluorimetrically at Excitation: 360 nm; Emission: 465 nm. Compounds are screened at 10 mM.

Substrate:

20 μM MALT1 substrate

Incubation:
