Oxysterol Binding Protein Proteins (OSBP)

Fruit Fly (Drosophila melanogaster) Oxysterol Binding Protein (OSBP) interaction partners

1. Study identified an OSBP- and FAN (show NSMAF Proteins)-mediated sterol requirement in Drosophila spermatogenesis

Human Oxysterol Binding Protein (OSBP) interaction partners

1. results demonstrate that Sac1 (show SACM1L Proteins) expression in either the ER or Golgi apparatus has a minimal impact on the PI-4P that regulates OSBP activity or recruitment to contact sites

2. Cholesterol transfer, PI4P consumption, and control of membrane lipid order by endogenous OSBP have been described.

3. Data suggest that OSBP shifts the distribution of phosphatidylinositol 4-phosphate upon localization to endoplasmic reticulum-Golgi contact sites.

4. Our results identify OspB as a regulator of mTORC1 and mTORC1-dependent cell proliferation early during S. flexneri infection and establish a role for IQGAP1 in mTORC1 signaling

5. These results suggest that poliovirus proteins modulate PI4KB (show PI4KB Proteins) activity and provide PI4P for recruitment of OSBP to accumulate unesterified cholesterol on virus-induced membrane structure for formation of a virus replication complex.

6. OSBP-mediated back transfer of phosphatidylinositol 4-phosphate might coordinate the transfer of other lipid species at the endoplasmic reticulum-Golgi interface.

7. OSBP is required for efficient replication of intracellular S. Typhimurium.

8. Data indicate that phosphorylation on two serine-rich motifs, S381-S391 (site 1) and S192, S195, S200 (site 2), specifically controls oxysterol-binding protein (OSBP) activity at the endoplasmic reticulum (ER).

9. PKD (show PRKD1 Proteins) negatively regulates HCV secretion/release by attenuating OSBP and CERT (show COL4A3BP Proteins) functions by phosphorylation inhibition. This study identifies the key role of the Golgi components in the HCV maturation process.

10. Results identify a novel substrate of protein kinase D (show PRKD1 Proteins) at the Golgi, the oxysterol-binding protein OSBP.

Mouse (Murine) Oxysterol Binding Protein (OSBP) interaction partners

1. OSBP may be a target and downstream effector of miR (show MLXIP Proteins)-124 for regulating neurite outgrowth and elongation.

2. Partitioning of Osbp between the endoplasmic reticulum and the Golgi apparatus is regulated by Vapa (show VAPA Proteins).

3. OSBP opposes the activity of LXR (show NR1H3 Proteins) by negatively regulating ABCA1 (show ABCA1 Proteins) activity in the cytoplasm by sterol-binding domain-dependent protein destabilization

Rabbit Oxysterol Binding Protein (OSBP) interaction partners

1. Oxysterol-binding protein is required for the perinuclear localization of intra-Golgi v-SNAREs.
