The beta 3-adrenoceptor plays a significant role in the control of lipolysis and thermogenesis in the brown adipose tissue of rodents and humans. In human beta 3-adrenoceptor, a Trp to Arg replacement has recently been discovered. This change which occurs at position 64, in the first coding exon, has been correlated with increased weight gain, difficulty in losing weight, insulin resistance syndrome, and worsened diabetic situation. Higher percentages of this mutation are observed in Pima Indians (over 30%) and Japanese (20%). The possible functional mechanism of Trp54Arg is reported using human HEK293 cell line stably expressing the wild type and the [Arg64] beta 3-adrenoceptor type. Beta 3-adrenoceptor agonists available for humans are been also developing. In this paper we describe these points up-to-date.
