General annotation (Comments)

Function

UCP are mitochondrial transporter proteins that create proton leaks across the inner mitochondrial membrane, thus uncoupling oxidative phosphorylation from ATP synthesis. As a result, energy is dissipated in the form of heat By similarity.

Subunit structure

Acts as a dimer forming a proton channel By similarity.

Subcellular location

Mitochondrion inner membrane; Multi-pass membrane protein Ref.5.

Tissue specificity

Highest in white adipose tissue, also detected in brown adipose tissue, heart and kidney. 4-6 times higher levels are detected in ob/ob and db/db mice.

Sequence similarities

Belongs to the mitochondrial carrier (TC 2.A.29) family. [View classification]

Contains 3 Solcar repeats.
