PRADC1: a novel metabolic-responsive secretory protein that modulates physical activity and adiposity.

ABSTRACT: Interorgan communication mediated by secreted proteins plays a pivotal role in metabolic homeostasis, yet the function of many circulating secretory proteins remains unknown. Here, we describe the function of protease-associated domain-containing 1 (PRADC1), an enigmatic secretory protein widely expressed in humans and mice. In metabolically active tissues (liver, muscle, fat, heart, and kidney), we showed that Pradc1 expression is significantly suppressed by refeeding and reduced in kidney and brown fat in the context of obesity. PRADC1 is dispensable for whole-body metabolism when mice are fed a low-fat diet. However, in obesity induced by high-fat feeding, PRADC1-deficient female mice have reduced weight gain and adiposity despite similar caloric intake. Decreased fat mass is att
