2019年3月27日 · In the present study, we hypothesized that MuRF1, a key gene involved in skeletal muscle mass loss, and its close counterpart MuRF2 play a role in skeletal muscle regeneration.
MuRF1 is a muscle fiber type II associated factor and together …
MuRF1 is a member of the RBCC (RING, B-box, coiled-coil) superfamily that has been proposed to act as an atrogin during muscle wasting. Here, we show that MuRF1 is preferentially expressed in type II muscle fibers. Five and 14 days after denervation, MuRF1 protein was further elevated but remained preferentially expressed in type-II muscle fibers.

2018年6月4日 · TRIM63 also known as muscle-specific RING finger protein-1 (MuRF1) is an E3 ubiquitin ligase that is expressed selectively in cardiac and skeletal muscles (Bodine et al., 2001).
Identification of the MuRF1 Skeletal Muscle Ubiquitylome …
MuRF1 (TRIM63) is a muscle-specific E3 ubiquitin ligase and component of the ubiquitin proteasome system. MuRF1 is transcriptionally upregulated under conditions that cause muscle loss, in both rodents and humans, and is a recognized marker of muscle atrophy.
Uncovering the mechanisms of MuRF1-induced ubiquitylation …
2024年3月1日 · The data presented here offers molecular insight into MuRF-induced ubiquitylation. We show that MuRF1 can interact with the UBE2D, E, N/V families and UBE2W during ubiquitylation. MuRF1 forms monoubiquitylation and creates K48- and K63-linked polyubiquitin chains in a UBE2 dependent manner.
Mechanisms of muscle atrophy and hypertrophy: implications in …
2021年1月12日 · Muscle-specific overexpression of IKKβ in transgenic mice leads to severe muscle wasting mediated, at least in part, by the ubiquitin ligase MuRF1, but not by atrogin-1/MAFbx 71.
MURF1 Antibody - Cell Signaling Technology
MURF1 Antibody detects endogenous levels of total MURF1 protein. Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human MURF1 protein. Antibodies were purified by protein A and peptide affinity chromatography.
