一次抗体 備考Furin is a membrane-associated, calcium-dependent, serine protease that belongs to the subtilisin-like prohormone convertase (PC) family. Members of this family of cellular enzymes cleave most prohormones and neuropeptide precursors. Numerous other cellular proteins, some viral proteins, and bacterial toxins that are transported by the constitutive secretory pathway are also targeted for maturation by PCs. Furin and other PC family members share structural similarities which include a heterogeneous ~10 kDa amino-terminal proregion, a highly conserved ~55 kDa subtilisin-like catalytic domain, and carboxyl-terminal domain that is heterogeneous in length and sequence. These enzymes become catalytically active following proregion cleavage within the appropriate cellular compartment. Furin is the only known PC to possess a transmembrane domain. Cleavage of target proteins occurs at the carboxyl-terminus of the furin consensus sequence, RX(K/R)R. It has been shown that the acidic peptide sequence, C771PSDSEEDEG780, localizes furin to the trans-Golgi-network. Phosphorylation of serine residues within this region modulates intracellular routing of Furin protein. An additional signaling domain includes the tetrapeptide sequence, Y759KGL762, which directs internalization from the cell surface.
Immunizing Peptide (Blocking)
Our Abpromise guarantee covers the use of ab3467 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||Use at an assay dependent concentration. Detects a band of approximately 100 kDa (predicted molecular weight: 87 kDa).Can be blocked with Furin peptide (ab4989).
Representing Furin in BSC-40 cells transfected with the human Furin gene.
機能Furin is likely to represent the ubiquitous endoprotease activity within constitutive secretory pathways and capable of cleavage at the RX(K/R)R consensus motif.
組織特異性Seems to be expressed ubiquitously.
配列類似性Belongs to the peptidase S8 family. Furin subfamily.
Contains 1 homo B/P domain.
ドメインContains a cytoplasmic domain responsible for its TGN localization and recycling from the cell surface.
翻訳後修飾The inhibition peptide, which plays the role of an intramolecular chaperone, is autocatalytically removed in the endoplasmic reticulum (ER) and remains non-covalently bound to furin as a potent autoinhibitor. Following transport to the trans Golgi, a second cleavage within the inhibition propeptide results in propeptide dissociation and furin activation.
Phosphorylation is required for TGN localization of the endoprotease. In vivo, exists as di-, mono- and non-phosphorylated forms.
細胞内局在Golgi apparatus > trans-Golgi network membrane. Cell membrane. Shuttles between the trans-Golgi network and the cell surface. Propeptide cleavage is a prerequisite for exit of furin molecules out of the endoplasmic reticulum (ER). A second cleavage within the propeptide occurs in the trans Golgi network (TGN), followed by the release of the propeptide and the activation of furin.

Predicted band size: 87 kDa
Observed band size: 63 kDa why is the actual band size different from the predicted?
Exposure time: 90 seconds
The band observed at 63 kDa could potentially be a cleaved form of Furin due to the presence of a 24 amino acid signal peptide and a 83 amino acid propeptide.
