Semaphorin-2A; Semaphorin 2a (Sema2a) encodes a secreted member of the semaphorin protein family. It utilizes the receptor encoded by PlexB to mediate both repulsive and attractive axon guidance. It also utilizes the transmembrane semaphorin encoded by Sema1a as a receptor for dendrite process guidance.

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.

Chemorepellent activity; semaphorin receptor binding; Belongs to the semaphorin family.

Semaphorin 5c (Sema5c) encodes a member of the Semaphorins family, which are membrane and secreted short-range signaling proteins. The product of Sema5c is involved in olfactory behavior.

Plexin A (PlexA) encodes a transmembrane receptor for Semaphorin ligands encoded by Sema1a and Sema1b. The intracellular region of this receptor has GTPase activating protein (GAP) activity on Ras/Rap small GTPases. The signaling by the product of PlexA alters actin, microtubules and cell adhesion in developmental processes such as axon guidance.

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-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 [...]

Cbl proto-oncogene (Cbl) encodes an E3 protein-ubiquitin ligase for protein post-translational modification in RTK signaling (EGFR, VEGFR, FGF, and RET families) and non-RTK signaling (Src family). After the ubiquitination mediated by the product of Cbl, the substrates will be targeted to protein degradation for controlling cell growth, survival, migration and inflammation.

Epidermal growth factor receptor; Binds to four ligands: Spitz, Gurken, Vein and Argos, which is an antagonist. Transduces the signal through the ras-raf-MAPK pathway. Involved in a myriad of developmental decisions. Critical for the proliferation of imaginal tissues, and for the determination of both the antero-posterior and dorso-ventral polarities of the oocyte. In the embryo, plays a role in the establishment of ventral cell fates, maintenance of amnioserosa and ventral neuroectodermal cells, germ band retraction, cell fate specification in the central nervous system and production [...]
