Activating transcription factor-2 (Atf-2) encodes a trancription factor required for heterochromatin assembly. It is involved in stress response and fat metabolism regulation.

MAP kinase-activated protein kinase 2; Its physiological substrate seems to be the small heat shock protein (HSP27/HSP25); Belongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family.

P38a MAP kinase (p38a) encodes a member of the mitogen-activated protein kinases responsive to diverse stresses. In immune response, it activates its downstream component encoded by Atf-2 that in turn regulates Duox expression.

Forkhead box protein O; Transcription factor involved in the regulation of the insulin signaling pathway. Consistently activates both the downstream target Thord4EBP and the feedback control target InR. Involved in negative regulation of the cell cycle, modulating cell growth and proliferation. In response to cellular stresses, such as nutrient deprivation or increased levels of reactive oxygen species, foxo is activated and inhibits growth through the action of target genes such as Thor. Foxo activated in the adult fat body can regulate lifespan in adults; an insulin peptide itself m [...]

Putative mitogen-activated protein kinase 14C; P38c MAP kinase (p38c) encodes a protein involved in the stress and wound responses, regulating the expression of Duox and Ddc.

Myocyte-specific enhancer factor 2; Transcription factor that could be a key player in early mesoderm differentiation and may be required for subsequent cell fate specifications within the somatic and visceral/heart mesodermal layers. Essential for myoblast fusion and consequently muscle formation in adults. During embryonic and pupal development, binds to the enhancer of the myoblast fusion gene sing and activates its transcription. Belongs to the MEF2 family.

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.

Puckered, isoform A; Puckered (puc) encodes a serine/threonine protein phosphatase that mediates a feedback loop that regulates the Jun-N-terminal kinase pathway.

Tyrosine-protein kinase Src64B; Src oncogene at 64B (Src64B) encodes a Src family nonreceptor tyrosine kinase. It has many biological roles, including ring canal morphogenesis in oogenesis and the male germline, microfilament ring constriction during cellularization, and modulation of growth and apoptosis. Some of its roles overlap with those of the product of Src42A.
