Summary: Enables GTPase activator activity. Involved in several processes, including cytoskeleton organization; embryonic morphogenesis; and open tracheal system development. Located in basolateral plasma membrane. Is expressed in several structures, including brain; fan-shaped body; imaginal disc; large field neurons; and wing vein. Used to study gonadal dysgenesis. Human ortholog(s) of this gene implicated in colorectal cancer. Orthologous to human DLC1 (DLC1 Rho GTPase activating protein); STARD13 (StAR related lipid transfer domain containing 13); and STARD8 (StAR related lipid transfer domain containing 8).

What's a GeneRIF?

Sleep deprivation increases the excitability of dorsal fan-shaped body neurons, but this homeostatic adjustment is disrupted in short-sleeping crossveinless-c mutants
Title: Neuronal machinery of sleep homeostasis in Drosophila.
We present evidence that low level of beta-integrin accumulation at the basal side of PCV epithelial cells regulated by Cv-C provides an optimal extracellular environment for guiding BMP transport
Title: A feed-forward loop coupling extracellular BMP transport and morphogenesis in Drosophila wing.
Dystrophin and the Rho GTPase crossveinless-c signaling pathway likely interact at the postsynaptic side of the NMJ to maintain synaptic homeostasis.
Title: The RhoGAP crossveinless-c interacts with Dystrophin and is required for synaptic homeostasis at the Drosophila neuromuscular junction.
Crossveinless-c (Cv-c) function is required in tissues actively undergoing morphogenesis to regulate RhoGTPase activity to promote the coordinated organisation of the actin cytoskeleton.
Title: crossveinless-c is a RhoGAP required for actin reorganisation during morphogenesis.
