The p38δ kinase isoform promotes brown adipose tissue thermogenesis, and its deletion leads to obesity and reduced energy expenditure.

In mice, the p38δ protein is required for fat-burning. Removing it causes obesity. This suggests that maintaining or activating p38δ in fat tissue could be a potential strategy to prevent obesity, though no human treatments exist yet.

lack of this kinase specifically in adipose tissue (p38δ Fab-KO) resulted in overweight together with reduced energy expenditure and lower body and skin surface temperature in the BAT region.
