WebJan 11, 2011 · MuRF1 contains a canonical N-terminal RING domain characteristic of RING-containing E3 ligases [ 44] followed by a MuRF family conserved region, zinc-finger domain (B-box) and leucine-rich coiled-coil domains, which allows it to form homo- and heterodimers with other MuRF proteins [ 104 ], and an acidic C′ terminal tail [ 10] (Fig. 1b ). Fig. 1 WebTwo key molecules involved in muscle atrophy, MAFbx/ atrogin 1 and MuRF1, are targets of miR-23a [74]. Ectopic expression of miR-23a is sufficient to protect muscles from dexamethasone-induced atrophy both in C2C12 myotubes and in adult mouse muscles. ...
