The chaperone-related p97 protein plays a central role in various cellular processes involving the ubiquitin-proteasome system. The diverse functions of p97 are controlled by a large number of cofactors that recruit specific substrates or influence their ubiquitylation state. Many cofactors bind through a UBX or PUB domain, two major p97 binding modules.(More)
AIMS Cardiac energy requirement is met to a large extent by oxidative phosphorylation in mitochondria that are highly abundant in cardiac myocytes. Human mitochondrial thioredoxin reductase (TXNRD2) is a selenocysteine-containing enzyme essential for mitochondrial oxygen radical scavenging. Cardiac-specific deletion of Txnrd2 in mice results in dilated(More)
