IGF2R

这个基因编码胰岛素样生长因子2和6-磷酸甘露糖的受体。每个配体的结合位点都位于蛋白质的不同片段上。该受体具有多种功能，包括溶酶体酶的细胞内转运、转化生长因子β的激活和胰岛素样生长因子2的降解。该基因的突变或杂合性丧失与肝癌的风险有关。直系小鼠基因被印记，显示来自母体等位基因的唯一表达；然而，人类基因的印记可能是多态的，因为只有少数个体显示来自母体等位基因的偏见表达（pmid:8267611）。[由RefSeq提供，2015年11月]
This gene encodes a receptor for both insulin-like growth factor 2 and mannose 6-phosphate. The binding sites for each ligand are located on different segments of the protein. This receptor has various functions, including in the intracellular trafficking of lysosomal enzymes, the activation of transforming growth factor beta, and the degradation of insulin-like growth factor 2. Mutation or loss of heterozygosity of this gene has been association with risk of hepatocellular carcinoma. The orthologous mouse gene is imprinted and shows exclusive expression from the maternal allele; however, imprinting of the human gene may be polymorphic, as only a minority of individuals showed biased expression from the maternal allele (PMID:8267611).
