MALT1 substrate – Antimicrobial Peptides – AMP

The optimal proteolytic substrate for mucosa-associated lymphoid tissue 1 (MALT1). MALT1 is an arginine-specific protease which cleaves after the C-terminal arginine residue. This peptide can be used to test MALT1 protease activity with the addition of an appropriate C-terminal tag. MALT1 has both adaptor and protease functions and is involved in controlling antigen receptor-mediated signalling to nuclear factor KB (NF-KB). When activated, MALT1 forms a complex with B-cell lymphoma/leukemia 10 (BCL10) and caspase recruitment domain-containing protein 11(CARD11)/CARD-containing MAGUK protein 1 (CARMA1), which results in NF-KB nuclear translocation. The protease function of MALT1 promotes gene transcription by inactivating negative regulators of NF-KB and JNK signalling, such as A20, RELB and CYLD. MALT1-dependent cleavage of the RNAse MCPIP1 (also known as Regnase-1) is then thought to lead to the stabilization of the resulting transcripts.
