Activation of Phosphotyrosine-Mediated Signaling Pathways in the Cortex and Spinal Cord of SOD1G93A, a Mouse Model of Familial Amyotrophic Lateral Sclerosis

open access: yesNeural Plasticity, 2018
Degeneration of cortical and spinal motor neurons is the typical feature of amyotrophic lateral sclerosis (ALS), a progressive neurodegenerative disease for which a pathogenetic role for the Cu/Zn superoxide dismutase (SOD1) has been demonstrated.

Domain Architecture of the Nonreceptor Tyrosine Kinase Ack1

open access: yesCells, 2023
The nonreceptor tyrosine kinase (NRTK) Ack1 comprises a distinct arrangement of non-catalytic modules. Its SH3 domain has a C-terminal to the kinase domain (SH1), in contrast to the typical SH3-SH2-SH1 layout in NRTKs.

A context‐dependent modulatory role for eIF6 in acquired resistance to vemurafenib in melanoma

open access: yesFEBS Letters, EarlyView.
Acquired resistance to vemurafenib upregulates the translation factor eIF6 in melanoma cells. Silencing eIF6 in resistant cells reduces proliferation and partially restores drug sensitivity, whereas its overexpression increases sensitivity across melanoma lines regardless of BRAF status, via modulation of mTOR, S6K, and MAPK signaling.

Phylogeny of Tec Family Kinases: Identification of a Pre-Metazoan Origin of Btk, Bmx, Itk, Tec, Txk and the Btk Regulator SH3BP5 [PDF]

open access: yes, 2008
It is generally considered mammals and birds have five Tec family kinases (TFKs): Btk, Bmx (also known as Etk), Itk, Tec, and Txk (also known as Rlk). Here, we discuss the domains and their functions and regulation in TFKs.

Tyrosine Kinase Inhibitors as Antiangiogenic Drugs in Multiple Myeloma

open access: yesPharmaceuticals, 2010
Tyrosine kinase inhibitors are a new class of anticancer drugs, that are capable of directly interacting with the catalytic site of the target enzyme and thereby inhibiting catalysis. Therapeutically useful tyrosine kinase inhibitors are not specific for

The ubiquitin system in normal and infected germinal center B cells

open access: yesFEBS Letters, EarlyView.
The ubiquitin system plays a central role in germinal center (GC) B cells, influencing differentiation to long‐lived memory B cells. Oncogenic gammaherpesviruses gain access to memory B cells by establishing latency in GC B cells. Mapping ubiquitin mechanisms in normal and infected GC B cells will define specific molecular circuits in B cells germane ...

Characterization of the function of a novel protein tyrosine phophatase predicted by the genome sequence of Arabidopsis thaliana [PDF]

open access: yes, 2003
Covalent modification of proteins by reversible phosphorylation, catalysed by specific protein kinases and phosphatases, is an important mechanism for enzyme activity regulation in metabolism and signalling pathways.

Involvement of protein tyrosine phosphatases in adipogenesis: New anti-obesity targets? [PDF]

open access: yesBMB Reports, 2012
Obesity is a worldwide epidemic as well as being a major riskfactor for diabetes, cardiovascular diseases and several types ofcancers. Obesity is mainly due to the overgrowth of adiposetissue arising from an imbalance between energy intake andenergy ...

Tyrosine phosphorylation of the BRI1 receptor kinase occurs via a posttranslational modification and is activated by the juxtamembrane domain

open access: yesFrontiers in Plant Science, 2012
In metazoans, receptor kinases control many essential processes related to growth and development and response to the environment. The receptor kinases in plants and animals are structurally similar but evolutionarily distinct and thus while most animal ...
