Phosphoinositide-binding protein which associates with both cell and endoplasmic reticulum(ER) membranes(PubMed:16143324). Can bind to the ER membrane protein VAPA and recruit VAPA to plasma membrane sites, thus linking these intracellular compartments(PubMed:25447204). The ORP3-VAPA complex stimulates RRAS signaling which in turn attenuates integrin beta-1(ITGB1) activation at the cell surface(PubMed:18270267, PubMed:25447204). With VAPA, may regulate ER morphology(PubMed:16143324). Has a role in regulation of the actin cytoskeleton, cell polarity and cell adhesion(PubMed:18270267). Binds to phosphoinositides with preference for PI(3,4)P2 and PI(3,4,5)P3(PubMed:16143324). Also binds 25-hydroxycholesterol and cholesterol(PubMed:17428193).
