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. -

ターゲット情報
-
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. - Information by UniProt

Immunocytochemistry - Anti-Furin antibody (ab3467)
Immunocytochemical analysis of methanol-fixed 2% BSA blocked HeLa cells strining furin with ab3467 at 2 µg/ml and labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate at 1/2000 dilution (green). Nuclei are stained with SlowFade® Gold Antifade Mountant with DAPI (blue), and the cytoskeleton with alpha-Tubulin Monoclonal Antibody and Goat anti-Mouse IgG Secondary Antibody, Alexa Fluor® 594 conjugate at 1/400 dilution (red). Negative control uses no primary antibody

Performed under reducing conditions.
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. -

Cells were fixed with paraformaldehyde, permeabilized using 0.1% Triton X-100, blocked with 1% BSA/ 5%FBS/PBS for 1 hour at 25°C and then incubated with ab3467 at a 1/100 dilution for 1 hour at 25°C. The secondary used was an Alexa-Fluor 546 conjugated goat anti-rabbit polyclonal used at a 1/500 dilution.
Cells were counterstained with DAPI (436nM, 5 mins) and Phalloidin-633 (1unit/coverslip) and mounted with prolong gold. No staining seen in secondary control and furin staining was punctate and throughout the cytoplasm.
