Study Discover Less-Known Protein Appears to Play Very Important Role in Metabolic Disease and Obesity

With unexpected findings of a protein that is extremely expressed in fat tissue, scientists at Scripps Research have opened the door to essential new understandings about obesity and metabolism. Their discovery, which seems Nov. 20 within the journal Nature, might result in new approaches for addressing obesity and probably many different illnesses.

 The signaling protein, known as PGRMC2, had not been extensively studied up to now. Brief for “progesterone receptor membrane component 2,” it had been detected within the uterus, liver, and a number of other areas of the body. However, the lab of Enrique Saez, Ph.D., noticed that it was most abundant in fats tissue—particularly in brown fat, which turns food into the warmth to take care of body temperature—and have become interested in its perform there.

The group constructed on their latest discovery that PGRMC2 binds to and releases a vital molecule referred to as heme. Recently, within the highlight for its function in offering flavor to the plant-primarily based Impossible Burger, heme holds a way more critical function within the body.

 The iron-containing molecule travels inside cells to enable crucial life processes comparable to cellular respiration, cell proliferation, cell death, and circadian rhythms. By means of research involving mice, the scientists established PGRMC2 as the primary intracellular heme chaperone to be described in mammals. Nevertheless, they did not cease there; they sought to seek out out what occurs within the body if this protein would not exist to move heme.

Brown fats, which is generally the best in heme content material, is usually thought of the “good fats.” One of its key roles is to generate heat to take care of body temperature. Among mice that have been unable to provide PGRMC2 of their fat tissues, temperatures dropped quickly when placed in a cold environment.
