DESCRIPTION

Also known as CUBN_HUMAN, CUBN, IFCR. Endocytic receptor which plays a role in lipoprotein, vitamin and iron metabolism by facilitating their uptake (PubMed:9572993, PubMed:10371504, PubMed:11717447, PubMed:11606717, PubMed:14576052). Acts together with LRP2 to mediate endocytosis of high-density lipoproteins, GC, hemoglobin, ALB, TF and SCGB1A1. Acts together with AMN to mediate endocytosis of the CBLIF-cobalamin complex (PubMed:9572993, PubMed:14576052). Binds to ALB, MB, Kappa and lambda-light chains, TF, hemoglobin, GC, SCGB1A1, APOA1, high density lipoprotein, and the CBLIF-cobalamin complex. Ligand binding requires calcium (PubMed:9572993). Serves as important transporter in several absorptive epithelia, including intestine, renal proximal tubules and embryonic yolk sac. May play an important role in the development of the peri-implantation embryo through internalization of APOA1 and cholesterol. Binds to LGALS3 at the maternal-fetal interface. Interacts with AMN (PubMed:14576052, PubMed:29402915, PubMed:20237569, PubMed:30523278). Component of the cubam complex composed of one CUBN trimer and one AMN chain (PubMed:30523278). The cubam complex can dimerize (By similarity). Interacts with LRP2 in a dual-receptor complex in a calcium-dependent manner. Found in a complex with PID1/PCLI1, LRP1 and CUBNI. Interacts with LRP1 and PID1/PCLI1.
