Neurexin 1, isoform F; Neurexin 1 (Nrx-1) encodes a transmembrane synaptic adhesive molecule that regulates the synaptic architecture and function in the brain and neuromuscular junction. It contributes to synaptic growth, transmission, synaptic formation and also regulation of learning and memory, locomotion and visual function.

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 GTPase activating protein at 93B; GTPase activator activity. It is involved in the biological process described with: positive regulation of GTPase activity; signal transduction; axon guidance; axon midline choice point recognition.

Bruchpilot, isoform J; Bruchpilot (brp) encodes a cytoskeletal protein critical for structural integrity of electron-dense projection (T-bar) at pre-active zones. It contributes to Ca[2+] channel clustering, size regulation of the synaptic vesicle readily releaseable pool and anesthesia-resistant memory formation.

Rho GTPase activating protein at 71E (RhoGAP71E) encodes a Rho GTPase activating protein that is involved in the regulation of actin dynamics during epithelial morphogenesis.

Dystrobrevin, isoform F; Zinc ion binding; structural constituent of muscle. It is involved in the biological process described with: synaptic signaling.

Rho GTPase-activating protein 190; GTPase-activating protein (GAP) for RhoA/Rho1 that plays an essential role in the stability of dorsal branches of mushroom body (MB) neurons. The MB neurons are the center for olfactory learning and memory. Acts by converting RhoA/Rho1 to an inactive GDP-bound state, leading to repress the RhoA/Rho1-Drok-MRLC signaling pathway thereby maintaining axon branch stability.

Ras-like GTP-binding protein RhoL; Essential for the maturation of hemocytes.

Cdc42 (Cdc42) encodes a GTPase signaling protein that acts as a molecular switch and functions as key regulator of the actin cytoskeleton. It plays a central role in diverse biological processes including actin cytoskeleton organization, mophogenesis, hemocyte migration, cell polarity, and wound repair.
