UCP1

A gene on chromosome 4q28-q31 that encodes one of the mitochondrial uncoupling proteins (UCP), which belong to the family of mitochondrial anion carrier proteins (MACPs). UCPs separate oxidative phosphorylation from ATP synthesis (the so-called mitochondrial proton leak); facilitate the transfer of anions from the inner to the outer mitochondrial membrane, and protons from the outer to the inner mitochondrial membrane; and reduce the mitochondrial membrane potential in mammalian cells. UCPs contain the 3 homologous protein domains of MACPs; UCP1 is expressed only in brown adipose tissue.

IGF2BP2 was originally identified as an RBP capable of binding IGF2 mRNA [9], and later studies suggest that it also targets other transcripts, such as LAMB2 [10], LIMS2 [11], TRIM54 [11], UCP1 [12], and 12 other genes encoding mitochondrial components [12].
