<n0:ComplexDefinition xmlns:n0="http://ncicb.nci.nih.gov/xml/owl/EVS/ComplexProperties.xsd#"><n0:def-definition>A protein family whose members are components of ubiquitin ligase complexes, which are involved in ubiquitination and proteasomal degradation of target proteins. Cullins may act as a scaffold to promote the association of substrates with ubiquitin-conjugating enzymes.</n0:def-definition><n0:def-source>NCI</n0:def-source></n0:ComplexDefinition>
