| Research Abstract |
Except in mouse, hyaluronan is a prominent constituent of the interphotoreceptor matrix (IPM), where it may serve to organize the matrix by functioning as a basic scaffold to which other macromolecules in the insoluble IPM are attached. Interactions between SPACR, a hyaluronan binding protein, and hyaluronan serve to form the basic macromolecular scaffold, which comprises the insoluble IPM. We previously showed expression of SPACR increases with age, paralleling the adhesion between neural retina and retinal pigment epithelium, indicating that SPACR might be involved in a system that mediates adhesion between neural retina and retinal pigment epithelium. Associations between SPACRCAN, another hyaluronan binding protein, and hyaluronan are also involved m the organization of the insoluble IPM. We continue to investigate the mechanism of the occurrence of adhesion between neural retina and retinal pigment epithelium generated by SPACR and SPACRCAN in corporation with other glycosaminoglycans, such as hyaluronan, heparan sulfates, and chondroitin sulfates.
