Ras-like GTP-binding protein Rho1

Gene

Rho1

Organism
Drosophila melanogaster (Fruit fly)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Has a role in regulating actin cytoskeletal organization: required during early development for proper execution of morphogenetic movements of individual cells and groups of cells important for the formation of the embryonic body plan (PubMed:10556060, PubMed:25739458). Plays a role in regulating dorsal closure during embryogenesis (PubMed:10556060, PubMed:10323867). During embryogenesis, acts upstream of wash to regulate the developmental migration of tail hemocytes anteriorly along the ventral midline (PubMed:25739458). May have a role in eye development (PubMed:7835340).4 Publications

Disruption phenotypei

Embryonic lethal. Embryos exhibit severe defects in head involution and imperfect dorsal closure. During head involution, the head structures fail to internalize resulting in holes in the dorsal anterior region of the cuticle. The disruption in the dorsal surface stretches the ventral surface, causing the cuticle to bow.1 Publication
