Pathway: Hemostasis (Homo sapiens)
Hemostasis is a physiological response that culminates in the arrest of bleeding from an injured vessel. Under normal conditions the vascular endothelium supports vasodilation, inhibits platelet adhesion and activation, suppresses coagulation, enhances fibrin cleavage and is anti-inflammatory in character. Under acute vascular trauma, vasoconstrictor mechanisms predominate and the endothelium becomes p

Pathway: Immune System (Homo sapiens)
Humans are exposed to millions of potential pathogens daily, through contact, ingestion, and inhalation. Our ability to avoid infection depends on the adaptive immune system and during the first critical hours and days of exposure to a new pathogen, our innate immune system

Pathway: Interleukin-3, 5 and GM-CSF signaling (Homo sapiens)
The Interleukin-3 (IL-3), IL-5 and Granulocyte-macrophage colony stimulating factor (GM-CSF) receptors form a family of heterodimeric receptors that have specific alpha chains but share a common beta subunit, often referred to as the common beta (Bc). Both subunits contain extracellular conserved motifs typical of the cytokine receptor superfamily. The cytoplasmic domains have limited similarity with o

Pathway: Growth hormone receptor signaling (Homo sapiens)
Growth hormone (Somatotropin or GH) is a key factor in determining lean body mass, stimulating the growth and metabolism of muscle, bone and cartilage cells, while reducing body fat. It has many other roles; it acts to regulate cell growth, differentiation, apoptosis, and reorganisation of the cytoskeleton, affecting diverse processes such as cardiac function, immune function, brain function, and aging

Pathway: Cytokine Signaling in Immune system (Homo sapiens)
Cytokines are small proteins that regulate and mediate immunity, inflammation, and hematopoiesis. They are secreted in response to immune stimuli, and usually act briefly, locally, at very low concentrations. Cytokines bind to specific membrane receptors, which then signal the cell via second messengers, to regulate cellular activity

Pathway: Factors involved in megakaryocyte development and platelet production (Homo sapiens)
Megakaryocytes (MKs) give rise to circulating platelets (thrombocytes) through terminal differentiation of MKs which release cytoplasmic fragments as circulating platelets. As MKs mature they undergo endoreduplication (polyploidisation) and expansion of cytoplasmic mass to cell sizes larger than 50-100 microns, and ploidy ranges up to 128 N. As MK's mature, the polyploid nucleus becomes horseshoe-shap

Pathway: Signaling by Interleukins (Homo sapiens)
Interleukins are low molecular weight proteins that bind to cell surface receptors and act in an autocrine and/or paracrine fashion. They were first identified as factors produced by leukocytes but are now known to be produced by many other cells throughout the body. They have pleiotropic effects on cells which bind them, impacting processes such as tissue growth and repair, hematopoietic homeostasis,

Reaction: SHP1 and SHP2 bind the common beta chain (Homo sapiens)
The common beta chain (Bc) has at least at least one direct binding site for SHP-1/SHP-2 (PTPN6/PTPN11). The SH2 domains of SHP1 and SHP2 associate with Y628 of Bc following IL-3 stimulation (Pei et al. 1994, Bone et al. 1997). SHPs act as regulators of signaling. SHP1 is thought to be a negative regulator of growth that terminates signals. Binding of SHP1 to EpoR leads to SHP1 activation and dephosph

Reaction: SH2B proteins bind JAK2 (Homo sapiens)
The SH2B family has 3 members sharing a common domain structure, including a dimerization domain, a pleckstrin homology (PH) region, and a SH2 domain. The SH2 domain binds phosphotyrosines of various signal-transducing proteins such as c-Kit, MPL, EpoR. All are able to bind JAK2 phosphorylated at Tyr-813 (Bersenev et al. 2008, Kurzer et al. 2004, 2006), inhibiting JAK2 proliferative signaling (Gery et

Reaction: SOCS binding to Ghr (Homo sapiens)
Supprossor of Cytokine Signaling (SOCS)1-3, and the related Cytokine-inducible SH2-containing protein (CIS) all bind tyrosine-phosphorylated GHR (Ram & Waxman 1999, Hansen et al. 1999). SOCS3 binding has been mapped to phosphorylated tyrosines Y338, Y333 (Ram & Waxman 1999), and Y487 (Hansen et al. 1999) in the membrane proximal region of the receptor. SOCS2 and CIS bind to residues Y487 and Y595 (Uytt
