of course we have as those that post here will already know combination of Jak1.
An excerpt follows which best read and understood and as far as I can see is the classic control of IL-6
Abstract
The shared cytokine receptor gp130 signals as a homodimer or heterodimer through activation of Janus kinases (Jaks) associated with the receptor intracellular domains. Here, we reconstitute, in parts and whole, the full-length gp130 homodimer in complex with the cytokine interleukin-6 (IL-6), its alpha receptor (IL-6Ra) and Jak1, for electron microscopy imaging. We find that the full-length gp130 homodimer complex has intimate interactions between the trans- and juxtamembrane segments of the two receptors, appearing to form a continuous connection between the extra- and intracellular regions. 2D averages and 3D reconstructions of full-length Jak1 reveal a three lobed structure comprising FERM-SH2, pseudokinase, and kinase modules possessing extensive intersegmental flexibility that likely facilitates allosteric activation. Single-particle imaging of the gp130/IL-6/IL-6Ra/Jak1 holocomplex shows Jak1 associated with the membrane proximal intracellular regions of gp130, abutting the would-be inner leaflet of the cell membrane. Jak1 association with gp130 is enhanced by the presence of a membrane environment.
Wow no more non classic disadvantage of the TyK 2 as the alternative signalling pathway covered by JAK1.
Surely it would be better to get hat an understanding that our TYK2 Jak1 inhibitor before persons prattle on about how much it is worth.
if it dont work there are no big bucks
Yes i do research completed my OU science degree 30 years ago. Bio chemistry and micro biology is not my specialised field. But I make an effort to learn even though getting on a bit.
My last post here so enjoy!
