Ring-finger protein 5 (RNF5), also known as RMA1, is a membrane-bound RING finger E3 ubiquitin ligase, which is conserved from worm to human. This protein is restricted to the dense bodies and the M-line of the body wall muscles. RNF5 is composed of a classic really interesting new gene (RING) domain, a single transmembrane-spanning domain and a formin-like homology domain. The RNF5 gene is mapped to human chromosome 6p21.32.
Specificity
Anti-RNF5 recognizes human RNF5.
Application
Anti-RNF5 antibody produced in rabbit is suitable for immunoblotting.
Biochem/physiol Actions
Ring-finger protein 5 (RNF5) is a component of the endoplasmic reticulum associated degradation (ERAD) machinery, where it has a role in ubiquitin-dependent degradation of misfolded proteins, such as mutant cystic fibrosis transmembrane conductance regulator (CFTR), as a part of the cell protein quality control. Deregulation of the RNF5 gene in endoplasmic reticulum (ER) stress is associated with muscular disorders. RNF5 regulates cell motility by targeting paxillin ubiquitination and altering the distribution and localization of paxillin in cytoplasm and cell focal adhesions. RNF5 is also involved in the regulation of cellular antiviral responses. High expression of the RNF5 gene is detected in breast cancer tumors and in melanoma, leukemia, ovarian and renal tumor-derived cell lines.
Physical form
Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
Storage and Stability
For continuous use, store at 2–8 °C for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing, or storage in “frost-free” freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilutions should be discarded if not used within 12 hours.

Many genomic loci have been identified for multiple sclerosis (MS) by genome-wide association studies (GWAS). Discrimination of the most functionally relevant genes in these loci remains challenging. The aim of this study was to highlight potential causal genes for MS.
The selective ubiquitination of proteins by ubiquitin E3 ligases plays an important regulatory role in control of cell differentiation, growth, and transformation and their dysregulation is often associated with pathologic outcomes, including tumorigenesis. RNF5 is an E3 ubiquitin ligase that
Viral infection activates transcription factors NF-kappaB and IRF3, which collaborate to induce type I interferons (IFNs) and elicit innate antiviral response. MITA (also known as STING) has recently been identified as an adaptor that links virus-sensing receptors to IRF3 activation.

Clearance of misfolded proteins by endoplasmic reticulum (ER)-associated degradation (ERAD) requires concerted activity of chaperones, adaptor proteins, ubiquitin ligases, and proteasomes. RNF5 is a ubiquitin ligase anchored to the ER membrane implicated in ERAD via ubiquitination of misfolded proteins. Among
It is known that seven mammalian selenoproteins are localized in the endoplasmic reticulum: SELENOM, SELENOT, SELENOF, SELENOK, SELENOS, SELENON, and DIO2. Among them, SELENOM and SELENOT are the least studied; therefore, the study of their function using the widespread method
