Osbpl8 Gene Summary [Rat]
Predicted to enable cholesterol binding activity; phosphatidylserine transfer activity; and phospholipid binding activity. Predicted to be involved in several processes, including fat cell differentiation; positive regulation of D-glucose import; and triglyceride homeostasis. Predicted to act upstream of or within negative regulation of cell migration; positive regulation of signal transduction; and protein localization to nuclear pore. Predicted to be located in cortical endoplasmic reticulum and nuclear membrane. Predicted to be active in cytosol and membrane. Orthologous to human OSBPL8 (oxysterol binding protein like 8).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Osbpl8 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
