| Function | Lipid-binding protein which promotes lipid absorption by facilitating MTTP-mediated lipid transfer (mainly triglycerides and phospholipids) and MTTP-mediated apoB lipoprotein assembly and secretion. Protects the gastrointestinal epithelium from irradiation-induced apoptosis. May play an important role in maintaining normal growth homeostasis in epithelial cells. Involved in p53/TP53-dependent cell survival after DNA damage. May down-regulate the expression of MAD1L1 and exert a suppressive role in mitotic spindle assembly checkpoint in hepatocellular carcinomas. |
