Association of the erythropoietin receptor with protein tyrosine kinase activity. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1992
We have examined the signal transduction mechanism of the hematopoietic growth factor erythropoietin (Epo). Epo stimulation of Ba/F3 cells transfected with the Epo receptor resulted in increases in tyrosine phosphorylation of proteins of 97, 75, and 55 kDa.

Genome-wide analysis to predict protein sequence variations that change phosphorylation sites or their corresponding kinases [PDF]

open access: yes, 2008
We define phosphovariants as genetic variations that change phosphorylation sites or their interacting kinases. Considering the essential role of phosphorylation in protein functions, it is highly likely that phosphovariants change protein functions and ...

Erythropoietin-induced serine 727 phosphorylation of STAT3 in erythroid cells is mediated by a MEK-, ERK-, and MSK1-dependent pathway [PDF]

open access: yes, 2003
Objective. Erythropoietin (EPO) is a key regulator of erythropoiesis, playing a role in both the proliferation and differentiation of erythroid cells.

Dammarenediol II enhances etoposide‐induced apoptosis by targeting O‐GlcNAc transferase and Akt/GSK3β/mTOR signaling in liver cancer

open access: yesMolecular Oncology, EarlyView.
Etoposide induces DNA damage, activating p53‐dependent apoptosis via caspase‐3/7, which cleaves PARP1. Dammarenediol II enhances this apoptotic pathway by suppressing O‐GlcNAc transferase activity, further decreasing O‐GlcNAcylation. The reduction in O‐GlcNAc levels boosts p53‐driven apoptosis and influences the Akt/GSK3β/mTOR signaling pathway ...

Novel protein kinase signaling systems regulating lifespan identified by small molecule library screening using Drosophila. [PDF]

open access: yesPLoS ONE, 2012
Protein kinase signaling cascades control most aspects of cellular function. The ATP binding domains of signaling protein kinases are the targets of most available inhibitors. These domains are highly conserved from mammals to flies.

Peptide G-Protein-Coupled Receptors and ErbB Receptor Tyrosine Kinases in Cancer

open access: yesBiology, 2023
The ErbB RTKs (EGFR, HER2, HER3, and HER4) have been well-studied in cancer. EGFR, HER2, and HER3 stimulate cancer proliferation, principally by activating the phosphatidylinositol-3-kinase and extracellular signal-regulated kinase (ERK) pathways ...

TYK2-induced phosphorylation of Y640 suppresses STAT3 transcriptional activity [PDF]

open access: yes, 2017
STAT3 is a pleiotropic transcription factor involved in homeostatic and host defense processes in the human body. It is activated by numerous cytokines and growth factors and generates a series of cellular effects.
