该基因编码蛋白质低密度脂蛋白受体家族的一个成员。编码的前蛋白由furin蛋白水解产生515kda和85kda亚单位，形成成熟受体（pmid:8546712）。该受体参与多种细胞过程，包括细胞内信号传导、脂质稳态和清除凋亡细胞。此外，编码蛋白对于α2-巨球蛋白介导的分泌型淀粉样前体蛋白和β-淀粉样蛋白的清除是必要的，β-淀粉样蛋白是阿尔茨海默病患者淀粉样斑块的主要成分阿尔茨海默病患者脑组织中该基因的表达随着年龄的增长而降低，并且低于对照组[由RefSeq提供，2015年10月]
This gene encodes a member of the low-density lipoprotein receptor family of proteins. The encoded preproprotein is proteolytically processed by furin to generate 515 kDa and 85 kDa subunits that form the mature receptor (PMID: 8546712). This receptor is involved in several cellular processes, including intracellular signaling, lipid homeostasis, and clearance of apoptotic cells. In addition, the encoded protein is necessary for the alpha 2-macroglobulin-mediated clearance of secreted amyloid precursor protein and beta-amyloid, the main component of amyloid plaques found in Alzheimer patients. Expression of this gene decreases with age and has been found to be lower than controls in brain tissue from Alzheimer's disease patients. [provided by RefSeq, Oct 2015]
