Abstract
RING-finger proteins play crucial roles in ubiquitination events involved in diverse cellular processes including signal transduction, differentiation and apoptosis. Most of the RING-finger proteins have E3-ubiquitin ligase activity. RNF11 is a small RING-finger protein and harbors a RING-H2 domain and a PY motif that could facilitate protein:protein interaction(s) involved in oncogenesis. To isolate RNF11 protein partners and determine its role in normal and cancer cells, we performed yeast two-hybrid screening. Among 18 in-frame positive clones, three were found to be ZBRK1, Eps15 and AMSH (associated molecule with the SH3 domain of STAM). ZBRK1 is a KRAB domain containing Zinc-finger protein and is known to repress target gene transcription in a BRCA1-dependent manner. Eps15 is monoubiquitinated and is part of an essential complex involved in the endocytosis of plasma membrane receptors via the clathrin-mediated internalization pathway. Recent studies have shown that AMSH protein is involved in BMP/TGF-β signaling pathway by binding to Smad6 and Smad7. The association of RNF11 with these binding partners suggests that it would be involved in biological processes such as gene transcription, BMP/TGF-β signaling and ubiquitination-associated events. Previously, we have shown that RNF11 interacts with the HECT-type E3 ligases AIP4 and Smurf2. Here, we show that RNF11 binds to AMSH in mammalian cells and that this interaction is independent of the RNF11 RING-finger domain and the PY motif. Our results also demonstrate that AMSH is ubiquitinated by Smurf2 E3 ligase in the presence of RNF11 and that a consequent reduction in its steady-state level requires both RNF11 and Smurf2. RNF11 therefore recruits AMSH to Smurf2 for ubiquitination, leading to its degradation by the 26S proteasome. The potential functions of RNF11-mediated degradation of AMSH in breast cancer are discussed.
