The muscle-specific RING-finger protein MuRF1 (also known as TRIM63) constitutes a bona fide ubiquitin ligase that routes proteins like several different myosin heavy chain proteins (MyHC) to proteasomal degradation during muscle atrophy. In two unbiased screens, we identified DCAF8 as a new MuRF1-binding partner. MuRF1 physically interacts with DCAF8 and both proteins localize to overlapping structures in muscle cells. Importantly, similar to what is seen for MuRF1, DCAF8 levels increasedoi:10.1242/jcs.233395 pmid:31391242 fatcat:mfrqqbp6bzdo7efssh4h5rpi7e
