LRP1B属于低密度脂蛋白（LDL）受体基因家族。由于这些受体与多种配体的相互作用，它们在正常细胞功能和发育中发挥着广泛的作用（Liu等人，2001[PubMed 11384978]）。
LRP1B belongs to the low density lipoprotein (LDL) receptor gene family. These receptors play a wide variety of roles in normal cell function and development due to their interactions with multiple ligands (Liu et al., 2001 [PubMed 11384978]).
