Protein
G protein-coupled receptor kinase 2
Gene
Gprk2, Gprk-2, CG17998
Organism
Drosophila melanogaster (Fruit fly)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Disruption phenotypei

Adult females show severely reduced number of egg chambers and the small germarium in ovarioles. The rare eggs that become fertilized display gross defects in embryogenesis exhibiting fusion of adjacent segments and holes in the dorsal and ventral cuticle.1 Publication

Expressioni

Tissue specificityi

Expressed in all larval tissues and in adult ovaries. Larval CNS staining is localized to axons projecting to the optic lobes and the mushroom bodies, in the longitudinal connectives, and in cell bodies and nerves of the ring gland corpus allatum. Adult CNS staining is detectable only in cell bodies and processes associated with the ellipsoid body of the central complex and portions of the mushroom bodies. In the wing disk, expression is confined to a stripe that parallels the anterior/posterior boundary of the wing blade and the hinge region, and weak expression in the prospective notum.1 Publication

Developmental stagei

Expressed both maternally and zygotically.1 Publication
