LRP1B屬于低密度脂蛋白（LDL）受體基因家族。由于這些受體與多種配體的相互作用，它們在正常細胞功能和發育中發揮著廣泛的作用（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]).
