It functions as an intracellular lipid transporter that binds oxysterols which are oxygenated derivatives of cholesterol. OSBP1 is involved in lipid exchange between the endoplasmic reticulum (ER) and the Golgi apparatus. It is expressed in various tissues with high levels observed in the liver brain and adipose tissue. OSBP1 facilitates the transport of sterols and phosphatidylinositol 4-phosphate (PI4P) influencing lipid metabolism and membrane formation.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nOSBP1 plays a significant role in maintaining cellular lipid homeostasis and is a part of the larger family of oxysterol-binding proteins. It participates in intracellular lipid transport and signaling aiding in the regulation of cholesterol metabolism. OSBP1 coordinates lipid exchange processes between the ER and other cellular compartments impacting membrane composition and function. Its activity is important for the generation of certain lipid domains contributing to cellular signaling pathways and membrane trafficking.\u003cbr\u003e\nPathways\u003cbr\u003e\nOSBP1 interacts within complex lipid signaling networks and is critically involved in the regulation of the phosphoinositide and cholesterol pathways. It collaborates with proteins such as VAP-A at membrane contact sites to exchange lipids like cholesterol and PI4P. This interaction is key to maintaining lipid gradients essential for multiple cellular functions including signaling and vesicle trafficking. Additionally OSBP1 modulates the activity of downstream phosphatidylinositol 4-kinases affecting phosphoinositide metabolism.\u003cbr\u003e\nOSBP1's dysregulation associates with abnormalities in lipid metabolism and related diseases. Such alterations can contribute to metabolic disorders like atherosclerosis due to its involvement in cholesterol transport and distribution. Furthermore OSBP1's function is linked to the pathogenesis of Niemann-Pick disease type C where cholesterol accumulation occurs. In these contexts OSBP1 operates in concert with other proteins such as Niemann-Pick C1 (NPC1) that participate in cholesterol trafficking and metabolism.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843892072617,"sku":"ab152583","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/es\/products\/abcam-ab152583","provider":"Iright","version":"1.0","type":"link"}
