Non-receptor tyrosine-protein kinase TYK2

TYK2 bind phosphotyrosineTYK2 a Janus kinase, contains a C-terminal protein tyrosine kinase catalytic domain and has no Nterminal signal peptide or transmembrane domain, of coding regions of exons and the adjacent intronic DNA sequences, identical to tyk2 of mutant Tyk2 forms deleted at the N terminus locus:19p13.2 [§§], a human mRNA (rs2304256) exon¤ encoding a non-receptor protein tyrosine kinase, the Tyk2 deficiency is likely to account for the phenotype by preventing* Tyk2 tyrosine phosphorylation for interferon (IFN) responses and Stat activation. STAT1 and STAT3 translocated to the nucleus following PAF (platelet-activating factor) stimulation in the presence of TYK2 in controlling responses to multiple cytokines IFNAR1 (the Tyr-based endocytic motif within) or PLAUR (a UPA receptor) urokinase signaling complex uPA containing TYK2 and phosphatidylinositol 3-kinase PI3K stabilized at the cell surface are downstream events binding to the type I IFN TYK2 the DNA-binding domainreceptor complex a pathway that supplements ISGF3/interferon-stimulated response element, and IRF5 a regulator. (IFNaR1) domain (dimerized) is required to induce phosphorylation of binding helical bundled cytokines and TYK2 phenotypes ability at binding and signal transduction to the nucleus for the acquisition of DNA binding activity, and modulates uPAR dependent functional responses in upregulation of C5aR* expression. Mutations in TYK2 and STAT3 mostly impair IL-6R* responses, and polymorphisms¤. Phenylephrine induced tyrosine phosphorylation of Jak2, Tyk2, and STAT1. TYK2, has an SH2 domain that contains a histidine instead of arginine (semi- vs essential amino acid) it may have lost the ability on ligand-induced signaling to bind phosphotyrosine at a neutral pH of 7. Either of the two Src homology 2(SH2)p85 domains binds the pseudokinase domain (a hypothetical masking complex) of TYK2 directly.

STAT1 signal transducer and activator of transcription 1

The JAK/STAT pathway signal transducer and activator of transcription STAT1 location: 2q32.2: [§§], is downstream of cytokine receptor IL2RG consisting of an N-terminal oligomerization domain surrounds a completely conserved arginine residue. And a C-terminal SRC homology-2 (SH2) domain and receptors which translocates GAF and  p48 ((protein 48), ISGF3) to the nucleus and upregulates in signal transduction from both the type I and type II interferons transcription of IFNG-regulated genes and protein inhibitor of the latent cytoplasmic transcription factor activated STAT1 PIAS1 (protein inhibitor of activated STAT1) interaction. Homeostatic balance antigen-driven proinflammatory chemokines and cytokine immune responses, are linked to a form of X-linked susceptibility, Nmi interacts with all STATs except Stat2, the (Stat) gene family has been highly conserved throughout evolution.

Saccharomyces cerevisiae, control STAT1 mRNA nuclear content that PIAS proteins promote, the nuclear pore-targeting of proteins that translocate into the nucleus and activate transcription in complex with mRNA (V: (−)ssRNA viruses, in a form deficient in DNA binding, enabling viruses to target– a Stat1 heterodimer, which lacks p48 a repressor region) to mycobacterial disease (disseminated BCG infection or vaccinated BCG locus: 2q32-37) that results in TYK2  Tyr701 note the two orange ** tags deficiency; in viral infection or other unidentified defects. ISGF3 binds to ISRE (interferon – stimulated response element) where they (STAT proteins) and their differences in IFN responsiveness (inducing a cell-mediated immunity) either act to or directly bind to DNA via signal transduction and activation of transcription after IFNG stimulation. STAT3 location: 17q21.2 is not activated by IFN-gamma but component p91 (IFN)-stimulated gene factor-3 known to be activated by JAKs the Janus kinases, which couple ligands IGF, IL6 and LIF dependent on the gp130-like leptin receptor (Obr) isoform, Stat3 gene C-terminal loop of the SH2 domain produced a molecule that dimerized (hetero- or homodimerize, and translocate to the nucleus) spontaneously, bound to DNA. Both signal transducer and activator of transcription factor 1 (STAT1) and STAT3 are activated in the liver.
