Abstract：
:Uncoupling proteins (UCPs), which dissipate the mitochondrial proton gradient, have the ability to decouple mitochodrial respiration from ATP production. Since mitochondrial electron transport is a major source of free radical production, it is possible that UCP activity might impact free radical production. Free radicals can react with and damage cellular proteins, DNA and lipids. Accumulated damage from oxidative stress is believed to be a major contributor to cellular decline during aging. If UCP function were to impact mitochondrial free radical production, then one would expect to find a link between UCP activity and aging. This theory has recently been tested in a handful of organisms whose genomes contain UCP1 homologs. Interestingly, these experiments indicate that UCP homologs can affect lifespan, although they do not support a simple relationship between UCP activity and aging. Instead, UCP-like proteins appear to have a variety of effects on lifespan, and on pathways implicated in lifespan regulation. One possible explanation for this complex picture is that UCP homologs may have tissue-specific effects that complicate their effects on aging. Furthermore, the functional analysis of UCP1 homologs is incomplete. Thus, these proteins may perform functions in addition to, or instead of, mitochondrial uncoupling. Although these studies have not revealed a clear picture of UCP effects on aging, they have contributed to the growing knowledge base for these interesting proteins. Future biochemical and genetic investigation of UCP-like proteins will do much to clarify their functions and to identify the regulatory networks in which they are involved.
