Featured Pathways
AHR is a cytosolic receptor for low molecular weight molecules, binding and becoming activated by sterically planar ligands approximately three benzene rings in size. It is maximally expressed in interface tissues including the liver, lungs, skin and gastrointestinal tract [Ref.1]. It is recognized as the culprit for most toxic responses observed after exposure to PAH (Polycyclic Aromatic[..]
To thwart viral infection, our cells have developed a formidable and integrated defense network that comprise of innate and adaptive immune responses. In an attempt to prevent viral replication, viral dissemination or persistent viral infection of the cell, many of these protective measures actually involve the induction of programmed cell death, or apoptosis. Once the virus has invaded the cell,[..]
AKT/PKB Pathway is an evolutionarily conserved serine/threonine kinase Pathway involved in a wide variety of cellular functions, including proliferation, cell survival, differentiation, glucose mobilization, homeostasis, cell migration, and apoptosis. Three isoforms, AKT1,AKT2, and AKT3, are expressed in mammals (Ref.1 & 2). Akt is a central node in cell signaling downstream of growth factors,[..]
ATM (Ataxia Telangiectasia Mutated Protein) belongs to a family of Kinases that have sequence homology to PI3K (Phosphoinositide 3-Kinase).ATM is a key regulator of multiple signaling cascades which respond to DNA strand breaks induced by damaging agents IR (Ionizing Radiation), radiometric agents or by normal processes. These responses involve the activation of cell cycle CHK factors[..]
The BCR (B-Cell antigen Receptor) plays a critical role in development, survival, and activation of B cells. The BCR is composed of mIg molecules (Membrane Immunoglobulin) and associated Ig-Alpha/Ig-Beta heterodimer [Ref.1]. The mIg subunits bind antigen and cause receptor aggregation, while the Alpha/Beta subunits transduce signals to the cell interior. Engagement of receptor activates three[..]
p14(ARF) is a key component of a major human tumor suppressor pathway that is responsible for arresting cell-cycle progression and inducing cell death in response to DNA damage and oncogenic stress. It plays an important role as an inhibitor of the MDM2-mediated degradation of p53. p14(ARF) activity is linked to its oligomerization and is sensitive to the redox status of the cell. Oxidative[..]
Tumor necrosis factor (TNF) superfamily proteins consisting of 19 members and 29 receptors regulate cell proliferation, cell death, and morphogenesis. The tumor necrosis factor superfamilies members provide key communication signals between various cell types during development, especially in the skin, bones, and lymphoid organs, and maintain organ homeostasis and initiate tissue responses.[..]
GPCRs (Guanine Nucleotide Binding–Protein Coupled Receptors) comprise large and diverse gene families in fungi, plants, and the animal kingdom. Also termed serpentine receptors, GPCRs are polytopic membrane proteins that share a common structure with seven transmembrane segments, but sequence similarity is minimal among the most distant GPCRs. Their principal function is to transmit[..]
Protein synthesis in eukaryotic organisms is a complex process that requires cooperation among a large number of polypeptides including ribosomal proteins, modification of enzymes, and ribosome-associated translation factors. The initiation phase of protein synthesis, during which ribosomes select mRNAs to be translated and identify the translational start site, requires a set of eIFs[..]
The ERBB (Erythroblastic Leukemia Viral Oncogene Homolog) family of transmembrane RTKs (Receptor Tyrosine Kinases) plays an important role in the pathogenesis of many cancers. This family is comprised of four members EGFR (Epidermal Growth Factor Receptor), ERBB2, ERBB3, and ERBB4, ERBB2 also called HER2 (Heregulin-2) and ERBB3 are closely related to the EGFR/ERBB1, but unlike EGFR, ERBB2 is a[..]
