Ras-like GTP-binding protein Rho1; 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. Plays a role in regulating dorsal closure during embryogenesis. During axis elongation, required for Rho-kinase Rok planar polarity and adherens junction localization as well as for generating a planar polarized distribution of the actin-binding protein Shrm. During embryogenesis, acts upstream of wash to regulate the d [...]

Rho guanine nucleotide exchange factor 2 (RhoGEF2) encodes a protein involved in actin organization and contractility. It contributes to multiple actin-based processes including wound healing, cell shape and cell contraction.

Rho GTPase activating protein at 54D, isoform A; GTPase activator activity. It is involved in the biological process described with: regulation of small GTPase mediated signal transduction; small GTPase mediated signal transduction; imaginal disc-derived leg morphogenesis.

Rho GTPase activating protein at 16F, isoform E; GTPase activator activity. It is involved in the biological process described with: positive regulation of GTPase activity; signal transduction; imaginal disc-derived leg morphogenesis; regulation of GTPase activity.

Crossveinless c (cv-c) encodes a RhoGTPase activating protein required for the morphogenesis of many tissues through the regulation of actin organization and localization of basement membrane receptors. It regulates synaptic homeostasis at the neuromuscular junction and is required for sleep homeostasis.

Ras-related protein Rac1; During various developmental processes, regulates changes in cell morphology in response to extracellular signals. During oogenesis, mediates signaling from the tyrosine kinase (RTK) chemoattractant receptors (Egfr and Pvr) to the guidance pathway that control the directional persistent collective migration of the border cell (BC) cluster through the nurse cells to the oocyte. Once activating by Pvr and Egfr, promotes the formation of forward-directed actin protrusions which stabilize the DE- cadherin (shg)-mediated adhesions. In turn, DE-mediated adhesion bet [...]

Ras GTPase-activating protein raskol; GTPase-activating protein, which acts as a negative regulator for some members of the Ras family (By similarity). Probably decreases their signaling activity by stimulating their intrinsic GTPase activity, thereby lowering the levels of the GTP-bound active form (By similarity). Functions with DE-cadherin (shg) to promote embryonic border cell (BC) migration and adhesion by regulating the distribution of actin protrusions in BCs. Promotes shg-mediated adhesion at the BC interfaces and likely maintains BC cluster adhesion during BC detachment from t [...]

Semaphorin-1A; Semaphorin 1a (Sema1a) encodes a transmembrane protein belonging to the semaphorin protein family. It is a repulsive axon guidance cue, signaling through direct interactions with the receptor encoded by PlexA, and also functions as a receptor to regulate dendrite targeting and axon guidance. Secreted semaphorins encoded by Sema2a and Sema2b can act as the product of Sema1a ligands.

Ras-related protein Rac2; Involved in integrin alpha-PS3/beta-nu-mediated phagocytosis of Gram-positive S.aureus by hemocytes.
