|Protein Name||Oxysterol-binding protein 1|
|Molecular Weight||89421 MW|
|Protein Function||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). .|
|Tissue Specificity||Widely expressed. .|
|Sequence Similarities||Belongs to the OSBP family.|
|Subcellular Localization||Cytoplasm. Golgi apparatus membrane; Peripheral membrane protein. When bound to oxysterols, translocates to the periphery of Golgi membranes.|
|Alternative Names||Oxysterol-binding protein 1;OSBP;OSBP1;|
|Research Areas|||cardiovascular|lipids / lipoproteins|lipid metabolism|cholesterol metabolism| signal transduction| metabolism|pathways and processes|metabolic signaling pathways|lipid and lipoprotein metabolism||

1. Post-translational modification:phosphorylation, methylation, glycosylation etc. These modifications prevent SDS molecules from binding to the target protein and thus make the band size appear larger than expected
2. Post-translational cleavage: this can cause smaller bands and or multiple bands
3. Alternative splicing: the same gene can have alternative splicing patterns generating different size proteins, all with reactivities to the antibody.
4. Amino Acid R chain charge: SDS binds to positive charges. The different size and charge of the Amino Acid side chains can affect the amount of SDS binding and thus affect the observed band size.
5. Multimers: Multimers are usually broken up in reducing conditions. However if the interactions between the multimers are strong, the band may appear higher.,
