3',5'-Cyclic Adenosine Monophosphate- and Ca2+-Calmodulin-Dependent Endogenous Protein Phosphorylation Activity in Membranes of the Bovine Chromaffin Secretory Vesicles: Identification of Two Phosphorylated Components as Tyrosine Hydroxylase and Protein Kinase Regulatory Subunit Type II [PDF]

open access: yes, 1983
: Membranes of the secretory vesicles from bovine adrenal medulla were investigated for the presence of the endogenous protein phosphorylation activity. Seven phosphoprotein bands in the molecular weight range of 250,000 to 30,000 were observed by means ...

Mechanisms and therapeutic opportunities of the ribotoxic stress response in cancer

open access: yesMolecular Oncology, EarlyView.
Cancer cells' high translational demand creates opportunities to therapeutically target ribosome function. Ribosome stalling and collisions activate ZAKα and the ribotoxic stress response (RSR), which can trigger rapid, p53‐independent apoptosis in cancer.

Hydroxyl Radical Induced Ultra-Weak Photon Emission from Tyrosine Solutions

open access: yes, 2015
This paper deals with ultra-weak photon emission (UPE) from aqueous tyrosine solutions induced by hydroxyl radical. The physical nature of this specific phenomenon is presented and the proposed mechanism of its origin during oxidation of tyrosine is ...

Transcriptomic insights into the effects of tyrosine on sub-Columbian plumage in H line chickens

open access: yesFrontiers in Veterinary Science
Tyrosine is known to influence melanin generation; however, its involvement in melanin production in chicken feathers is unknown. We evaluated the feather color of H-line chickens fed diets containing different concentrations of tyrosine (0, 0.4, 0.6, 0 ...

Novel Strecker degradation products of tyrosine and dihydroxyphenylalanine

open access: yesCzech Journal of Food Sciences, 2001
Tyrosine was oxidised with either potassium peroxodisulphate or glyoxal. Volatile reaction products were isolated and analysed by GC/FID and GC/MS, derivatised with diazomethane and analysed by the same methods.

The VHL tumor suppressor at the crossroad of protein folding, aggregation, and cancer

open access: yesMolecular Oncology, EarlyView.
Mutations, environmental stress, and chaperone dysfunction can destabilize pVHL, promoting its conversion from the native folded state into amyloid‐like assemblies. This transition may contribute to protein storage, cell dormancy, survival, and drug resistance.

pharmacological application of tyrosine kinase inhibitors in certain malinancies

open access: yes, 2019
The use of targeted therapy to inhibit tyrosine kinases, as a form of cancer chemotherapy is one of the major medical advances in the past decade. Tyrosine kinases activate many signal transduction cascades by adding a phosphate group to proteins and ...
