| Research Abstract |
Collectins are a family of C type lectins which have collagen-like sequences and carbohydrate recognition domains (CRD). The scavenger receptors type A and MARCO are classical type scavenger receptors which have internal collagen-like domains. Here, we found a new scavenger receptor which is a membrane type collectin from placenta (collectin placenta 1=CL-P1) that has a typical collectin collagen-like domain and a CRD. To elucidate the functions in CL-P1 in animal body is our purpose. In 3 years, we finished seven projects below,
1.Cloning of CL-P1 cDNA in human, mouse, rat, zebra fish, xenopus.
2.Establishment of CL-P1 permanent expression cells.
3.Production of soluble recombinant CL-P1 and mutant one having deletion or point mutation.
4.Discovery of binding protein against CL-P1.
5.Analyses oxidized LDLs after having different oxidation treatment.
6.Study on the promoter activity in CL-P1 5'-franking region.
7.Study on the kinetics of CL-P1 after several physiological treatments.
