Osbp Gene Summary [Mouse]
Predicted to enable several functions, including phosphatidylinositol-4-phosphate binding activity; sterol binding activity; and sterol transfer activity. Predicted to be involved in several processes, including positive regulation of insulin secretion involved in cellular response to glucose stimulus; positive regulation of secretory granule organization; and positive regulation of tyrosine phosphorylation of STAT protein. Predicted to be located in several cellular components, including Golgi apparatus; nuclear lumen; and perinuclear region of cytoplasm. Predicted to be active in cytosol; perinuclear endoplasmic reticulum; and plasma membrane. Is expressed in several structures, including central nervous system; genitourinary system; immune system; liver; and retina nuclear layer. Orthologous to human OSBP (oxysterol binding protein).

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 mouse Osbp often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
