CARD14-Mediated Activation of Paracaspase MALT1 in Keratinocytes: Implications for Psoriasis
Mutations in caspase recruitment domain-containing protein 14 (CARD14) have been linked to susceptibility to psoriasis. CARD14 is an intracellular scaffold protein that regulates proinflammatory gene expression. Recent studies have offered novel insights into the mechanisms of CARD14-mediated signaling in keratinocytes and the molecular impact of psoriasis-associated CARD14 mutations. CARD14 forms a signaling complex with BCL10 and the paracaspase MALT1, and this process is enhanced upon pathogenic CARD14 mutation, culminating in the activation of MALT1 protease activity and psoriasis-associated gene expression.
