Leber congenital amaurosis linked to AIPL1: a mouse model reveals destabilization of cGMP phosphodiesterase.
Leber congenital amaurosis (LCA4) has been linked to mutations in the photoreceptor-specific gene Aryl hydrocarbon interacting protein like 1 (Aipl1). To investigate the essential role of AIPL1 in retina, we generated a mouse model of LCA by inactivating the Aipl1 gene. In Aipl1(-/-) retinas, the outer nuclear layer develops normally, but rods and cones then quickly degenerate. Aipl1(-/-) mice ...
متن کاملThe expression of the Leber congenital amaurosis protein AIPL1 coincides with rod and cone photoreceptor development.
PURPOSE The Leber congenital amaurosis (LCA) protein AIPL1 is present only in the rod photoreceptors of the adult human retina and is excluded from the cone photoreceptors. LCA, however, is characterized by an absence of both rod and cone function at birth or shortly thereafter. Therefore, this study was conducted to determine whether AIPL1 is present in the rod and cone photoreceptors of the d...
متن کاملThe Leber congenital amaurosis protein, AIPL1, is needed for the viability and functioning of cone photoreceptor cells.
Leber congenital amaurosis (LCA) caused by mutations in Aryl hydrocarbon receptor interacting protein like-1 (Aipl1) is a severe form of childhood blindness. At 4 weeks of age, a mouse model of LCA lacking AIPL1 exhibits complete degeneration of both rod and cone photoreceptors. Rod cell death occurs due to rapid destabilization of rod phosphodiesterase, an enzyme essential for rod survival and...
متن کاملThe Leber Congenital Amaurosis Protein AIPL1 and EB Proteins Co-Localize at the Photoreceptor Cilium
PURPOSE The aim of this study was to investigate the interaction and co-localization of novel interacting proteins with the Leber congenital amaurosis (LCA) associated protein aryl hydrocarbon receptor interacting protein-like 1 (AIPL1). METHODS The CytoTrapXR yeast two-hybrid system was used to screen a bovine retinal cDNA library. A novel interaction between AIPL1 and members of the family ...
متن کاملThe Leber congenital amaurosis protein AIPL1 functions as part of a chaperone heterocomplex.
PURPOSE AIPL1 mutations cause the severe inherited blindness Leber congenital amaurosis (LCA). The similarity of AIPL1 to tetratricopeptide repeat (TPR) cochaperones that interact with the chaperone Hsp90 and the ability of AIPL1 to suppress the aggregation of NUB1 fragments in a chaperone-like manner suggest that AIPL1 might function as part of a chaperone heterocomplex facilitating retinal pr...
