Ras-related protein Rap1; Rap1 GTPase (Rap1) encodes a small GTPase in the Ras superfamily. When GTP bound, it binds to a number of different effectors, one of which is the product of scno. Together they regulate many morphogenetic movements including mesoderm invagination and dorsal closure, help establish apical-basal polarity during cellularization, regulate macrophage migration, help define neuroblast asymmetric division, and play a role in planar cell polarity in the imaginal discs.

Abelson interacting protein (Abi) encodes a protein that interacts with the non-receptor tyrosine kinase encoded by Abl. It contributes to the regulation of actin cytoskeleton organization. It is involved in multiple actin dependent processes including cell adhesion, cell morphogenesis, oogenesis, muscle attachment and axogenesis.

Rhea, isoform B; Rhea (rhea) encodes fly talin, a large adaptor protein that is essential for all adhesive functions of integrins. It also has at least one role independent of integrins: repressing shg transcription in follicle cells.

Adapter molecule Crk; Adapter protein which interacts with C-terminal portion of mbc, homolog of human DOCK180. May play a role in cellular processes throughout development; Belongs to the CRK family.

C-terminal Src kinase (Csk) encodes a cytoplasmic tyrosine kinase that acts as a tumor suppressor through Src pathway inibition as well as a mediator of the activity of the product of Egfr.

Enabled (ena) encodes the sole Drosophila member of the Ena/VASP family. It acts as a processive actin polymerase, stimulating actin addition at the barbed end. It has roles in both epithelial morphogenesis and CNS pathfinding.

Protein enhancer of sevenless 2B; Downstream of receptor kinase (drk) encodes an adaptor protein that recognizes phosphorylated tyrosine residues of membrane receptors and triggers the Ras/Raf/MAPK pathway. drk product contributes to the regulation of cytoskeletal organization and participates in developmental and cognitive processes (associative learning, anesthesia resistant memory).

SHC-adaptor protein (Shc) encodes a protein involved in receptor tyrosine kinase signalling. It regulates anti-parasitoid immune response and tracheal development.

Ras-like protein 1; Ras proteins bind GDP/GTP and possess intrinsic GTPase activity (By similarity). Plays a role in eye development by regulating cell growth, survival of postmitotic ommatidial cells and differentiation of photoreceptor cells. During larval development, mediates Ptth/tor signaling leading to the production of ecdysone, a hormone required for the initiation of metamorphosis.
