Roles of the tyrosine isomers meta- tyrosine and ortho- tyrosine in oxidative stress [PDF]

open access: yesAgeing Research Reviews, 2016
The damage to cellular components by reactive oxygen species, termed oxidative stress, both increases with age and likely contributes to age-related diseases including Alzheimer's disease, atherosclerosis, diabetes, and cataract formation. In the setting of oxidative stress, hydroxyl radicals can oxidize the benzyl ring of the amino acid phenylalanine,

Archaeal tyrosine recombinases

open access: yesFEMS Microbiology Reviews, 2021
ABSTRACTThe integration of mobile genetic elements into their host chromosome influences the immediate fate of cellular organisms and gradually shapes their evolution. Site-specific recombinases catalyzing this integration have been extensively characterized both in bacteria and eukarya.

Structural basis of tubulin tyrosination by tubulin tyrosine ligase [PDF]

open access: yesJournal of Cell Biology, 2013
Tubulin tyrosine ligase (TTL) catalyzes the post-translational retyrosination of detyrosinated α-tubulin. Despite the indispensable role of TTL in cell and organism development, its molecular mechanism of action is poorly understood. By solving crystal structures of TTL in complex with tubulin, we here demonstrate that TTL binds to the α and β subunits

The Rotational Spectrum of Tyrosine [PDF]

open access: yesThe Journal of Physical Chemistry A, 2015
In this work neutral tyrosine has been generated in the gas phase by laser ablation of solid samples, and its most abundant conformers characterized through their rotational spectra. Their identification has been made by comparison between the experimental and ab initio values of the rotational and quadrupole coupling constants.

Tyrosine supplementation for phenylketonuria [PDF]

open access: yesCochrane Database of Systematic Reviews, 2010
Phenylketonuria is an inherited disease for which the main treatment is the dietary restriction of the amino acid phenylalanine. The diet has to be initiated in the neonatal period to prevent or reduce mental handicap. However, the diet is very restrictive and unpalatable and can be difficult to follow.

Agrin-induced acetylcholine receptor clustering in mammalian muscle requires tyrosine phosphorylation. [PDF]

open access: yes, 1996
Agrin is thought to be the nerve-derived factor that initiates acetylcholine receptor (AChR) clustering at the developing neuromuscularjunction. We have investigated the signaling pathway in mouse C2 myotubes and report that agrin induces a rapid but ...

Tyrosine kinase inhibitors for the therapy of anaplastic thyroid cancer [PDF]

open access: yes, 2015
Anaplastic thyroid cancer (ATC) is often incurable so new therapeutic approaches are needed. Tyrosine kinases inhibitors (such as imanitib, sunitinib or sorafenib) are under evaluation for the treatment of ATC.

Insights into PI3K/AKT signaling in B cell development and chronic lymphocytic leukemia

open access: yesFEBS Letters, EarlyView.
This Review explores how the phosphoinositide 3‐kinase and protein kinase B pathway shapes B cell development and drives chronic lymphocytic leukemia, a common blood cancer. It examines how signaling levels affect disease progression, addresses treatment challenges, and introduces novel experimental strategies to improve therapies and patient outcomes.

NLRP3 tyrosine phosphorylation is controlled by protein tyrosine phosphatase PTPN22 [PDF]

open access: yesJournal of Clinical Investigation, 2016
Inflammasomes form as the result of the intracellular presence of danger-associated molecular patterns and mediate the release of active IL-1β, which influences a variety of inflammatory responses. Excessive inflammasome activation results in severe inflammatory conditions, but physiological IL-1β secretion is necessary for intestinal homeostasis. Here,

The cytoskeletal control of B cell receptor and integrin signaling in normal B cells and chronic lymphocytic leukemia

open access: yesFEBS Letters, EarlyView.
In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.
