Binds LDL, the major cholesterol-carrying lipoprotein of plasma, and transports it into cells by endocytosis. Binds the receptor-associated protein (RAP). Could play a role in cell-cell interaction. Publication Abstract from PubMed Sorting-related receptor with A-type repeats (SORLA) is an important receptor for regulating normal cellular functions via protein sorting. Here, we determined the structures of the full-length SORLA and identified two distinct conformations of apo-SORLA using single-particle cryogenic electron microscopy. In contrast to homologous proteins, both monomer and dimer forms of SORLA existed in a neutral solution. Only three hydrogen bonds in the vicinity of the dimer interface implied the involvement in dimerization. The orientation of residue R490 was a key point for ligand binding. These results suggest a unique mechanism of SORLA dimerization for protein trafficking. Cryo-EM structures reveal distinct apo conformations of sortilin-related receptor SORLA.,Zhang X, Wu C, Song Z, Sun D, Zhai L, Liu C Biochem Biophys Res Commun. 2022 Apr 16;600:75-79. doi: , 10.1016/j.bbrc.2022.01.108.
