Rho-type guanine nucleotide exchange factor (RtGEF) encodes a putative Rho-type guanine nucleotide exchange factor for the GTPases encoded by Rac1 and Cdc42. It signals through the sterile-20 kinases encoded by Pak and hpo. The product of RtGEF contributes to regulation of postsynaptic structure, post synaptic muscle development, protein localization and the growth of epithelial tissue.

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 [...]

Dreadlocks, isoform B; It is involved in the biological process described with: axon guidance; myoblast fusion; negative regulation of insulin receptor signaling pathway.

Mig-2-like (Mtl) encodes a Rho GTPase involved in actin organization regulation. It contributes to multiple actin-mediated processes including dorsal closure, wound healing, cell migration, germ band shortening and salivary gland morphogenesis.

Non-specific serine/threonine protein kinase; Pak3 (Pak3) encodes a Ser/Thr kinase implicated in myoblast fusion, synapse development, wound healing and border cell migration. It functions downstream of the small Rac GTPases to regulate actin cytoskeletal organization.

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

LIM domain kinase 1 (LIMK1) encodes a protein that belongs to a phylogenetically conserved family of serine/threonine kinases. It is a potent stabilizer of the actin cytoskeleton by inactivating the product of tsr. It stabilizes the synapse structure at the neuromuscular junction and promotes synaptic remodeling and glomerular development in the developing antennal lobe.

Moesin/ezrin/radixin homolog 2; Regulator of the Hippo/SWH (Sav/Wts/Hpo) signaling pathway, a signaling pathway that plays a pivotal role in organ size control and tumor suppression by restricting proliferation and promoting apoptosis. The core of this pathway is composed of a kinase cascade wherein Hippo (Hpo), in complex with its regulatory protein Salvador (Sav), phosphorylates and activates Warts (Wts) in complex with its regulatory protein Mats, which in turn phosphorylates and inactivates the Yorkie (Yki) oncoprotein. Mer acts synergistically along with Ex and Kibra to regulate t [...]

G protein-coupled receptor kinase interacting ArfGAP (Git) encodes an Arf-GAP that forms a scaffold with the Rho-type guanine nucleotide exchange factor encoded by pix aiding in activation of the kinase encoded by Pak. The product of RtGEF has roles in muscle morphogenesis, synaptic vesicle recycling, and regulation of tissue growth.
