摘要： Scavenger receptors (SRs) play critical roles in various physiological and pathological pathways. One of them, CD163, is a multifunctional endocytic receptor and is characterized by a long-range scavenger receptor cysteine-rich (SRCR) repeat. However, the structural and functional details of this long-range SRCR repeat have not yet been elucidated. In this study, the CD163 long-range SRCR repeat was expressed in Drosophila Schneider 2 cells. The recombinant protein was homogeneous after purification by metal-affinity, cation-exchange and size-exclusion chromatography. Single crystals were obtained using 20% PEG 4000, 0.15 M potassium sodium tartrate tetrahydrate pH 8.5 and diffracted to 3.30 angstrom resolution. As the first view of a long-range SRCR repeat, this work lays the structural basis for a deep understanding of SRs and their multiple functions.
