Dual specificity mitogen-activated protein kinase kinase dSOR1; Required downstream of Raf in the sevenless (sev), torso (tor), and Drosophila EGF receptor homolog (DER) signal transduction pathways. Involved in both positive regulation (at the posterior terminus) and negative regulation (at the anterior domain) of tll, as in other terminal class gene products, maybe via the ERK-A kinase. Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. MAP kinase kinase subfamily.

Extracellular signal-regulated kinase 7; Atypical MAPK protein that regulates protein secretion in a kinase activity-dependent manner. In response to starvation regulates protein secretion by mediating transitional endoplasmic reticulum site disassembly. Mediates inhibition of insulin-like peptide secretion upon disturbed ribosome biogenesis and acts as a downstream effector of TP53.

Dual specificity protein phosphatase Mpk3; Negatively regulates the activity of members of the MAP kinase family in response to changes in the cellular environment. Has a specificity for the ERK family. Acts as negative regulator in a variety of developmental processes including cell differentiation and proliferation controlled by the Ras/ERK pathway. Suppresses the photoreceptor cell differentiation and wing vein formation. Required for proper oogenesis and early embryogenesis. Functions autonomously in a subset of photoreceptor progenitor cells in eye imaginal disks. Appears also to [...]

Leucine-rich repeat protein soc-2 homolog; Acts as a Ras effector and participates in MAPK pathway activation. Probably acts as a regulatory subunit of protein phosphatase that specifically dephosphorylates Raf kinase and stimulate Raf activity at specialized signaling complexes upon Ras activation (By similarity); Belongs to the SHOC2 family.

Tyrosine-protein phosphatase corkscrew; Required in all receptor tyrosine kinase signaling pathways. Functions downstream of the receptor tyrosine kinase torso, acting in concert with D-Raf via tailless. Also functions downstream of Egfr (epidermal growth factor receptor) and btl (fibroblast growth factor receptor). The SH2 domain suggests that csw effects its role by mediating heteromeric protein interactions. Maternally required for normal determination of cell fates at the termini of the embryo. Required for cell fate specification of the ventral ectoderm, in the developing embryoni [...]

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.

P38b MAP kinase (p38b) encodes the serine/threonine kinase that constitutes MAP kinase signaling cascades. It is phosphorylated by MAPK kinases and phosphorylates various substrates that play roles in stress responses, immune responses and differentiation; Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MAP kinase subfamily.

FI01116p; Transcription coactivator activity; nucleic acid binding. It is involved in the biological process described with: regulation of gene expression; positive regulation of transcription by RNA polymerase II.

Protein son of sevenless; Promotes the exchange of Ras-bound GDP by GTP. Functions in signaling pathways initiated by the sevenless and epidermal growth factor receptor tyrosine kinases; implies a role for the ras pathway in neuronal development.
