RTK Signaling
Receptor Tyrosine Kinases (RTKs) are membrane bound kinases that are activated upon binding of receptor specific ligands. They make up the largest class of membrane receptors that trigger signaling cascades through their inherent enzymatic activity. These structures, activation mechanisms and key components of the signaling pathways are highly conserved in metazoans. There are 58 known RTKs in humans, which are grouped into 20 classes depending on topology.
RTKs are fairly promiscuous receptors, and activating stimuli comprise a plethora of growth factors, hormones, and cytokines. Most RTKs form dimers and become active upon ligand binding. The active RTK phosphorylates activators of downstream signaling cascades such as NF-kB, MAPK, Ca2+ dependent signaling, and the JAK-STAT pathway.
RTKs affect a wide spectrum of processes ranging from cytoskeleton dynamics, cell growth and differentiation to inflammation, apoptosis, and tumor progression. In spite of the exceptionally high variety of receptors and outcomes, RTKs engage only a limited set of core processes. Therefore, quantitative analysis of factors like an RTK’s expression profile are crucial for the understanding of the signaling processes and predicting qualitative outcomes.

Regulator
EIF4EBP1 (Eukaryotic Translation Initiation Factor 4E Binding Protein 1):
This gene encodes one member of a family of translation repressor proteins. The protein directly interacts with eukaryotic translation initiation factor 4E (eIF4E), which is a limiting component of the multisubunit complex that recruits 40S ribosomal subunits to the 5' end of mRNAs. Interaction of this protein with eIF4E inhibits complex assembly and represses translation. This protein is...

RHEB (Ras Homolog Enriched in Brain):
This gene is a member of the small GTPase superfamily and encodes a lipid-anchored, cell membrane protein with five repeats of the RAS-related GTP-binding region. This protein is vital in regulation of growth and cell cycle progression due to its role in the insulin/TOR/S6K signaling pathway. The protein has GTPase activity and shuttles between a GDP-bound form and a GTP-bound form, and...

Transcription factor
JUN - C-JUN
This gene is the putative transforming gene of avian sarcoma virus 17. It encodes a protein which is highly similar to the viral protein, and which interacts directly with specific target DNA sequences to regulate gene expression. This gene is intronless and is mapped to 1p32-p31, a chromosomal region involved in both translocations and deletions in human malignancies. [provided by RefSeq, Jul...

NFATC1 (Nuclear Factor of Activated T-Cells, Cytoplasmic, Calcineurin-Dependent 1):
The product of this gene is a component of the nuclear factor of activated T cells DNA-binding transcription complex. This complex consists of at least two components: a preexisting cytosolic component that translocates to the nucleus upon T cell receptor (TCR) stimulation, and an inducible nuclear component. Proteins belonging to this family of transcription factors play a central role in...

NFkBP65 - p65
NF-kappa-B is a ubiquitous transcription factor involved in several biological processes. It is held in the cytoplasm in an inactive state by specific inhibitors. Upon degradation of the inhibitor, NF-kappa-B moves to the nucleus and activates transcription of specific genes. NF-kappa-B is composed of NFKB1 or NFKB2 bound to either REL, RELA, or RELB. The most abundant form of NF-kappa-B is...

STAT1 (Signal Transducer and Activator of Transcription 1, 91kDa):
The protein encoded by this gene is a member of the STAT protein family. In response to cytokines and growth factors, STAT family members are phosphorylated by the receptor associated kinases, and then form homo- or heterodimers that translocate to the cell nucleus where they act as transcription activators. This protein can be activated by various ligands including interferon-alpha,...

STAT3 (Signal Transducer and Activator of Transcription 3 (Acute-Phase Response Factor)):
The protein encoded by this gene is a member of the STAT protein family. In response to cytokines and growth factors, STAT family members are phosphorylated by the receptor associated kinases, and then form homo- or heterodimers that translocate to the cell nucleus where they act as transcription activators. This protein is activated through phosphorylation in response to various cytokines and...

ABI1 (Abl-Interactor 1):
This gene encodes a member of the Abelson-interactor family of adaptor proteins. These proteins facilitate signal transduction as components of several multiprotein complexes, and regulate actin polymerization and cytoskeletal remodeling through interactions with Abelson tyrosine kinases. The encoded protein plays a role in macropinocytosis as a component of the WAVE2 complex, and also forms a...

ARPC1B (Actin Related Protein 2/3 Complex, Subunit 1B, 41kDa):
This gene encodes one of seven subunits of the human Arp2/3 protein complex. This subunit is a member of the SOP2 family of proteins and is most similar to the protein encoded by gene ARPC1A. The similarity between these two proteins suggests that they both may function as p41 subunit of the human Arp2/3 complex that has been implicated in the control of actin polymerization in cells. It is...

ACTR2 (ARP2 Actin-Related Protein 2 Homolog (Yeast)):
The specific function of this gene has not yet been determined\; however, the protein it encodes is known to be a major constituent of the ARP2/3 complex. This complex is located at the cell surface and is essential to cell shape and motility through lamellipodial actin assembly and protrusion. Two transcript variants encoding different isoforms have been found for this gene. [provided by...
