In the evolving field of molecular biology, the study of ubiquitin-proteasome pathways has become a cornerstone for understanding protein turnover. One specific molecule that often surfaces in high-level research is the Fbx32 peptide. Often recognized by its alternative nomenclature, Atrogin-1 or MAFbx, this protein plays a critical role in cellular degradation processes.
What is Fbx32?
FBXO32 (F-box protein 32) is a specialized gene that encodes a protein b This antibody detects a 41 kDa protein corresponding to the apparent molecular mass ofFbx32on SDS-PAGE immunoblots of mouse muscle tissue lysates.Read more elonging to the F-box family. This family is structurally characterized by an approximately 114907 - Gene ResultFBXO32 F-box protein 32 [ (human)] 40 amino acid motif known as the F-box. At a functional level, Fbx32 serves as the substrate-recognition component of the Skp1-Cul1-F-box (SCF) E3 ubiquitin-protein ligase complex. This complex is essential for mediating the ubiquitination and subsequent degradation of target proteins via the proteasome.
From a structural perspective, FBXO32 is a member of the Fbxs class of the F-box protein family, and it is specifically expressed in cardiac and skeletal muscle. Given its high expression levels during muscle atrophy, it has become a focal point for researchers examining muscle protein homeostasis.

Sequence similarities.Read more ry analysis, the Fbx32 Blocking Peptide is an essential tool for verifying the specificity of antibody staining. By utilizing a Polyclonal Fbx32 Antib Anti-Fbx32 Antibody (A82571) ody or a specialized Fbx32/FBOX32 Rabbit pAb, researchers can perform immunodepletion or competition assays to ensure their results are accurate.
When selecting reagents, many researchers look for specific validation:
* Fbx32 antibody LS-C456707 and Fbx32 antibody LS-B9748 are frequently cited for their utility in Western Blot (WB) and Immunohistochemistry (IHC) applications.
* The Fbx32 Antibody is often a rabbit monoclonal antibody detecting Fbx32, which provides high affinity and consistency across various experimental setups.
* Because these reagents can be used in a variety of model species—including Canine, Equine, Human, Mouse, Porcine, Rabbit, Rat, and Zebrafish—they offer significant versatility for comparative studies.
Technical Considerations for Research
When sourcing a Recombinant Human FBXO32 Protein or a synthetic peptide, it is vital to consider the molecular weight, which typically migrates at approximately 41–42 kDa on SDS-PAGE. Whether you are using a FBXO32 Antibody for Western Blot or immunofluorescence, the quality of the immunogen—often derived from specific sequences like amino acids 206-355—is paramount.
Key Insights for Researchers:
1. Specificity: Always confirm that your chosen reagent is validated for you FBXO32 Antibodyis a Rabbit Polyclonal antibody against FBXO32. This gene encodes a member of the F-box protein family which is characterized by an r specific model species.
2. Application: Ensure the antibody or peptide is compatible with your target application, such as ELISA, IHC, or Western Blot.
3. Context: Remember that FBXO32 Polyclonal Antibody | Invitrogen (PA5-91959) Fbx32, also known as Atrogin-1 or MAFbx, is highly expressed during muscle atrophy, which is why it remains a subject of intense investigation in muscle biology.
By integrating these specialized tools into your workflow, you can better characterize the role of the E3 ligase pathway. Whether conducting metabolic research or exploring the mechanisms of protein degradation, the use of high-quality Fbx32 reagents remains the standard for robust, reproducible data in the laboratory environment.
