<p>VEGF (also called PDGF or PVF) pathway participates in different developmental processes,
including border cell migration, hemocyte migration and survival, thorax closure during
metamorphosis, the rotation and dorsal closure of the male terminalia. and embryonic salivary
gland tissue migration.
The ability of PVR to activate the MAP-kinase pathway is important for control of cell growth
and differentiation in other tissues.
Three genes in the Drosophila genome code for PVR ligands: PVF1, PVF2, and PVF3.
Binding of one of the ligands (PVF1, 2 or 3) to the receptor PVR triggers the canonical
DRK/SOS/RAS/RAF/DSOR1/RL pathway (Ducheck et al., 2001; Brückner et al., 2004; Wood et al., 2006; Harris et al., 2007; Sims et al., 2009)..
DOF is needed to assemble the PVR receptor and allow it to auto-phosphorylate, likely as an
adaptor that links the receptor to RAS pathway.
DOF is a cytoplasmic protein which is expressed ubiquitously only in cells that express the FGF
receptors. It contains an ankyrin repeat, a coiled-coil structure and many tyrosines within environments that suggest that if phosphorylated they act as binding sites for the SH2 domains of proteins such as DRK or CSW (Vincent et al, 1998).
The SH2-domain-containing protein DRK recruits the guanine nucleotide exchange factor, Son
of sevenless (SOS), to catalyze the exchange of GDP bound to RAS for GTP, thereby activating
RAS with the help of activated KSR.
RAS promotes the activation of RAF, leading to the activation of DSOR1, and ultimately to that
of the MAP kinase Rolled (RL ).
Rolled can activate transcription, both through inactivation of transcriptional co-repressors such as AOP, as well as through the activation of transcription factors such as the ETS-domain-containing protein Pointed (PNT) (ONeill et al, 1994; Brunner et al, 1994).
The activation of PNT is a major output of the pathway. It is either phosphorylated by MAP
kinase to produce an active transcriptional activator (PointedP2), or transcriptionally induced by
MAP kinase to produce a constitutive transcriptional activator (PointedP1).
Sprouty (STY) acts downstream of the receptor, but upstream of RAS1 and RAF, by recruiting
GAP1 and blocking the ability of DRK to bind to its positive effector.
We have considered three typical initial states corresponding to
i. ligands binding in wild-type signalling enabling situation (VEGF_signalling),
ii. ligand binding in the presence of the inhibitor Sprouty (Sprouty_inhibition),
iii. absence of ligand (No_signalling).</p>

PVF2 and PVF3 have a similar expression pattern and may originate from a duplication, and are functionally similar to each other (Cho et al, 2002). Sims et al, 2009 further showed that PVF2 and PVF3 act redundantly to activate PVR.</p>

Sprouty acts upstream of Ras1 and Raf, by recruiting Gap1 and blocking the ability of Drk to bind to its positive

<p>Connector Enhancer of KSR (CNK) activity is required for various RTK-mediated developmental events and affect cell proliferation/survival, differentiation and migration (Therrien et al, 1998; Baonza et al, 2000; Cabernard and Affolter, 2005).
CNK directly associates with the kinase domain of RAF via a short amino-acid sequence, called the RAF-interacting motif (RIM), and modulates RAF activity according to the RTK signalling status (Douziech et al, 2003; Laberge et al, 2005). Without signalling, CNK binding is inhibited by a second motif adjacent to the RIM, called the inhibitory sequence (IS). Upon pathway activation, CNK integrates SRC42 and RAS activities, which then lead to RAF activation. The binding of SRC42 to an RTK-dependent phospho-tyrosine residue (pY1163) located at the C-terminal of the IS motif appears to release the inhibitory effect that the IS motif imposes on RAF catalytic function (Laberge et al, 2005). Functional analysis indicated that CNK acts downstream of RAS, but at a step upstream of RAF. </p>

<p>The moleskin gene encodes Drosophila Importin-7 (DIM-7). MSK/DIM-7 is a member of the importin superfamily of nuclear importers, which can bind directly to the nuclear pore complex (Gorlich et al, 1997; Jakel et al, 1999).
In Drosophila, MSK/DIM-7 is tyrosine phosphorylated in response to growth factor stimulation of RTKs, and it
physically binds Rolled (Lorenzen et al, 2001). MSK is a General RL Nuclear Import Factor.
