PIAS Factors from Rainbow Trout Control NF-κB- and STAT-Dependent Gene Expression.

Four 'protein inhibitors of activated STAT' (PIAS) control STAT-dependent and NF-κB-dependent immune signalling in humans. The genome of rainbow trout () contains eight genes, which encode at least 14 different transcripts that are differentially expressed in a tissue- and cell-specific manner. was the most strongly expressed variant among the analysed genes in most tissues, while was commonly low or absent.
