Biological background
Protein function (datasheet): Involved in the processing of hormone and other protein precursors at sites comprised of pairs of basic amino acid residues.
Scientific background (datasheet): PCSK4 (Proprotein Convertase, Subtilisin/Kexin-Type, 4), is an enzyme that in humans is encoded by the PCSK4 gene. The gene for PC4 (Pcsk4 locus) was mapped to mouse chromosome 10, close to the adipsin locus and near the gene encoding anti-mullerian hormone. Qiu et al. (2005) found that aberrant processing of pro-IGF2 by PC4 may be a cause of IUGR. PC4 cleaved pro-IGF2 to generate the intermediate processed form, IGF2 (1-102). Mature IGF2 (1-67), likely resulting from further processing by carboxypeptidases, is capable of activating invasive trophoblast cells through AKT phosphorylation. Inhibition of PC4 by a PC4-specific inhibitor blocked pro-IGF2 processing and reduced trophoblast cell migration.
Cellular localization (datasheet): Cytoplasmic vesicle, secretory vesicle. Localized in the secretion granules.
Tissue details (datasheet): Expressed abundantly in the testis. .
Sequence similarities (datasheet): Belongs to the peptidase S8 family. Furin subfamily.
Research relevance and current trends
- Commonly studied in contexts related to Cell Biology,Proteolysis/Ubiquitin,Proteolytic Enzymes.
- Supports comparative expression analysis across conditions, genotypes, or treatments when paired with appropriate controls.
- Useful for confirming target presence and subcellular distribution using orthogonal readouts (e.g., microscopy vs. immunoblotting).
Common research applications
- Western blot (WB): Compare relative target abundance and apparent size/isoforms across samples; interpret bands in light of expected MW and potential PTMs.
- ELISA: Measure target abundance in compatible matrices using a standard-curve readout; ensure dilution linearity and appropriate controls.
- Immunohistochemistry (IHC): Assess tissue distribution and cell-type patterns; interpret staining with appropriate negative controls and antigen context.
- Flow cytometry: Quantify target-positive populations in single-cell suspensions; pair with viability and isotype/FMO controls conceptually.
Notes for experimental interpretation
- Consider isoforms, post-translational modifications, and processing that can shift apparent molecular weight or localization.
- Cross-reactivity (datasheet): No cross-reactivity with other proteins
- Use appropriate positive and negative controls (e.g., KO/KD, blocking peptide, or isotype controls) to support specificity interpretation.
As a polyclonal antibody, this reagent may recognize multiple epitopes on the target, which can improve detection robustness but may require careful specificity controls.
