| Title | Molecular cloning and functional characterization of a human scavenger receptor with C-type lectin (SRCL), a novel member of a scavenger receptor family. |

| Abstract |
Using a human placenta cDNA library, we cloned a novel member belonging to the scavenger receptor family. Complementary DNA of this clone encodes a type II transmembranous glycoprotein containing a collagen-like domain, which are typical structural characteristics of scavenger receptor class A. This protein also contains a C-type lectin/carbohydrate recognition domain (C-type CRD) located at the C-terminus. We designated this as Scavenger Receptor with C-type Lectin (SRCL) type I. We also isolated human SRCL type II, which lacks the C-type CRD. Northern blot analysis revealed that hSRCL type I and type II mRNAs are abundantly expressed in adult human tissues. When hSRCL type I and type II were expressed in CHO-K1 cells, they were localized in the plasma membrane forming clusters on the surface. Ligand-binding studies of CHO-K1 cells expressing hSRCL type I and type II demonstrated their specific binding capacity in Escherichia coli and Staphylococcus aureus. These results indicate that hSRCL is a novel bacteria-binding receptor containing a C-type CRD and this receptor may play an important role in host defense. |
