Primary antibody notes
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. -

Developed using the ECL technique.
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.
