Biological background
Protein function (datasheet): Binds cholesterol and a range of oxysterols including 25-hydroxycholesterol (PubMed:15746430, PubMed:17428193). Cholesterol binding promotes the formation of a complex with PP2A and a tyrosine phosphatase which dephosphorylates ERK1/2, whereas 25-hydroxycholesterol causes its disassembly (PubMed:15746430). Regulates cholesterol efflux by decreasing ABCA1 stability (PubMed:18450749). .
Scientific background (datasheet): OSBP (Oxysterol-Binding Protein), also called OSBP1, is a protein that in humans is encoded by the OSBP gene. Im et al. (2005) reported the structure of the full-length yeast oxysterol-binding-protein Osh4, a member of the OSBP-related protein (ORP) family, at 1.5- to 1.9-angstrom resolution in complexes with ergosterol, cholesterol, and 7-, 20- and 25-hydroxy cholesterol. Moreira et al. (2001) refined the localization of the OSBP1 gene to chromosome 11q12.1 by radiation hybrid analysis. Wang et al. (2005) found that OSBP functions as a cholesterol-binding scaffolding protein coordinating the activity of 2 phosphatases to control the extracellular signal-regulated kinase (ERK) signaling pathway. Cytosolic OSBP formed an approximately 440-kD oligomer with a member of the PTPPBS family of tyrosine phosphatases, the serine/threonine phosphatase PP2A, and cholesterol.
Cellular localization (datasheet): Cytoplasm. Golgi apparatus membrane; Peripheral membrane protein. When bound to oxysterols, translocates to the periphery of Golgi membranes.
Tissue details (datasheet): Widely expressed. .
Sequence similarities (datasheet): Belongs to the OSBP family.
Research relevance and current trends
- Commonly studied in contexts related to Cardiovascular,Cholesterol Metabolism,Lipid and Lipoprotein Metabolism,Lipid Metabolism,Lipids/Lipoproteins,Metabolic Signaling Pathways,Metabolism,Pathways and Processes,Signal Transduction.
- 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.
