Biological background

P4HB (protein: Lysosome-associated membrane glycoprotein 2 (Lamp2)) is a commonly studied target in molecular and cellular biology. Functional context (as provided): Binds to and inhibits the transcriptional repressor ZBTB33, which may lead to activation of target genes of the Wnt signaling pathway (By similarity). Associates with and regulates the cell adhesion properties of both C-, E- and N-cadherins, being critical for their surface stability. Implicated both in cell transformation by SRC and in ligand-induced receptor signaling through the EGF, PDGF, CSF-1 and ERBB2 receptors. Promotes GLIS2 C-terminal cleavage. . Reported cellular localization context: Cytoplasm. Nucleus. Cell membrane. Interaction with GLIS2 promotes nuclear translocation (By similarity). Detected at cell-cell contacts. NANOS1 induces its translocation from sites of cell-cell contact to the cytoplasm. Isoforms 4A and 1AB are excluded from the nucleus. . Tissue expression notes (as provided): Expressed in vascular endothelium. Melanocytes and melanoma cells primarily express the long isoform 1A, whereas keratinocytes express shorter isoforms, especially 3A. The shortest isoform 4A, is detected in normal keratinocytes and melanocytes, and generally lost from cells derived from squamous cell carcinomas or melanomas. The C-terminal alternatively spliced exon B is present in the p120ctn transcripts in the colon, intestine and prostate, but lost in several tumor tissues derived from these organs. .

Research relevance and current trends

• Research context keywords from the source record include: Stem Cells.
• Current studies often focus on connecting target abundance/localization to pathway perturbations across models, tissues, and cell states.
• Quantitative and multiplexed assays (e.g., imaging + immunoblot panels) are commonly used to compare phenotypes across conditions and time-courses.

Common research applications

• Western blotting (WB): assess relative target abundance across samples, treatments, or time-points.
• Immunohistochemistry (IHC): evaluate spatial distribution of target-positive staining in tissue architecture.
• Immunofluorescence/ICC (IF/ICC): visualize subcellular localization patterns and cell-to-cell heterogeneity.
• Flow cytometry: quantify target-positive populations and compare shifts in marker distributions.

Workflow ideas (metafield): Validate P4HB antibody specificity using KO/KD control samples (WB/IF/IHC as appropriate), Detect P4HB expression by Western blot in cell or tissue lysates, Detect P4HB in FFPE tissue sections by immunohistochemistry, Localize P4HB by immunofluorescence/immunocytochemistry in cultured cells, Quantify P4HB-positive cells by flow cytometry in single-cell suspensions

Notes for experimental interpretation

• Consider isoforms and post-translational modifications (PTMs) that may shift apparent molecular weight or epitope accessibility.
• Apparent molecular weight may vary by sample type and processing (observed MW: 57 kDa; calculated MW: 108170 MW).
• Control concepts: include appropriate negative controls (e.g., isotype, KO/KD samples) and orthogonal validation when feasible.
