Identification of a novel protein interacting with RPGR

Identification of a novel nurr1-interacting protein.

The orphan nuclear receptor Nurr1 is required for the development of ventral mesencephalic dopaminergic neurons in mice. One of the possible mechanisms that might contribute to the regulation activity of Nurr1 is through interaction with other proteins. To identify potential partners of Nurr1, we screened a yeast two-hybrid library from developing mouse embryonic mesencephalon with the Nurr1 li...

An RPGR interacting protein is associated with the cilium

The retinitis pigmentosa GTPase regulator (RPGR)- interacting protein: subserving RPGR function and participating in disk morphogenesis.

Retinitis pigmentosa is a photoreceptor degenerative disease leading to blindness in adulthood. Leber congenital amaurosis (LCA) describes a more severe condition with visual deficit in early childhood. Defects in the retinitis pigmentosa GTPase regulator (RPGR) and an RPGR-interacting protein (RPGRIP) are known causes of retinitis pigmentosa and LCA, respectively. Both proteins localize in the...

Identification of neurabin II as a novel doublecortin interacting protein

The neuronal migration protein doublecortin (DCX) that associates with microtubules through a tandem DCX repeat, is required for the development of the complex architecture of the human cerebral cortex. Using a yeast two-hybrid screen with Dcx as bait, we have isolated neurabin II/spinophilin, an F-actin binding protein known to play a role in dendritic spine formation. The coiled-coil domain o...

Identification of a novel RPGR exon ORF15 mutation in a family with X-linked retinitis pigmentosa.

OBJECTIVE To investigate the phenotypic and genotypic characteristics of a novel mutation associated with X-linked retinitis pigmentosa (XLRP). METHODS Six individuals in a family with XLRP were recruited, and clinical examinations were performed. All of the members were genotyped with microsatellite markers at loci that were considered to be associated with XLRP. The retinitis pigmentosa GTP...
