TRIM-NHL Proteins Take on miRNA Regulation

The TRIM-NHL family of proteins is conserved among metazoans and has been shown to regulate cell proliferation and development. In this issue, Hammell et al. (2009) and Schwamborn et al. (2009) identify two members of this protein family, NHL-2 in worms and TRIM32 in mice, as positive regulators of microRNA function.

TRIM proteins: New players in virus-induced autophagy

Autophagy is an evolutionarily conserved and intricately regulated cellular process in which damaged or aggregated proteins, organelles, and pathogen-derived components are engulfed by double-membrane structures, termed autophagosomes, and targeted for lysosomal degradation [1]. The autophagic process consists of distinct phases that include nucleation, autophagosome formation, selection of car...

Tumor Metabolism: MAGE-A Proteins Help TRIM Turn Over AMPK

MAGE-A proteins are testis-specific E3 ubiquitin ligase components whose expression is upregulated in many cancers. MAGE-A3 and -A6 act as oncogenes and recent work now shows that they degrade the central metabolic regulator AMPK, providing a novel mechanism for rewiring cancer metabolism.

Functional interactions between ubiquitin E2 enzymes and TRIM proteins.

The TRIM (tripartite motif) family of proteins is characterized by the presence of the tripartite motif module, composed of a RING domain, one or two B-box domains and a coiled-coil region. TRIM proteins are involved in many cellular processes and represent the largest subfamily of RING-containing putative ubiquitin E3 ligases. Whereas their role as E3 ubiquitin ligases has been presumed, and i...
