CD45 is a pan-leukocyte protein with tyrosine phosphatase activity involved in the regulation
of signal transduction in hematopoiesis.
Klemke's interests, and what he envisions to be the future
of signal transduction research, is finding which of these signals are active — which are phosphorylated and dephosphorylated, for instance — during cancer cell metastasis.
Understanding the nature of this intrinsic activity will require integrating knowledge from cognitive and systems neuroscience with cellular and molecular neuroscience where ion channels, receptors,
components of signal transduction and metabolic pathways are all in a constant state of flux.
An important one of these is its role as a natural inhibitor
of signal transduction by hedgehog (a hormone involved in morphogenesis).
«The Cancer Genome Atlas is a really rich and growing database of publicly available data created to help us understand cancer,» said Horvath, who is a program
co-leader of the Signal Transduction in Cancer program at the Lurie Cancer Center.
Recent studies such as ours, however, establish protein phosphatases as positive and essential
regulators of signal transduction, with remarkable substrate specificity and coordinated activities.
Aside of the
inhibition of signal transduction, on - target repositioning assumes that the targets recognized in nematods, such as mitochondrial respiration and microtubules, are hit in cancer cells [70, 89, 90].
Several projects in the
area of signal transduction, fluorescent proteins engineering, optogenetics and advanced microscopy are available.
During the early years of my PhD studies, I was very fascinated by the exciting discoveries in the
field of signal transduction, in particular how receptor tyrosine kinases are activated to transmit their signals and how protein complexes are formed through defined protein folds (domains) interacting with specific cellular targets.
Biophysical and cell biological studies are carried out in conjunction with measurements of cellular activities so as to determine what features are critical for the initiation and
regulation of signal transduction.
