Affinity for the Interface Underpins Potency of Antibodies Operating In Membrane Environments
(Cell Press, 2020-08-18)
The contribution of membrane interfacial interactions to recognition of membrane-embedded antigens by antibodies is currently unclear. This report demonstrates the optimization of this type of antibodies via chemical ...
Using a Simple Cellular Assay to Map NES Motifs in Cancer-Related Proteins, Gain Insight into CRM1-Mediated NES Export, and Search for NES-Harboring Micropeptides
(MDPI, 2020-09-01)
The nuclear export receptor CRM1 (XPO1) recognizes and binds specific sequence motifs termed nuclear export signals (NESs) in cargo proteins. About 200 NES motifs have been identified, but over a thousand human proteins ...
Calcium effect on dynamics and stability of KV7.2 channel
(2020-09-29)
La familia Kv7 controla la excitación celular en diferentes tejidos, por lo que es importante investigar su fisiología y fisiopatología. Se relaciona con enfermedades como la epilepsia, encefalopatías, arritmias, diabetes ...
Fluorescence Microscopy of the HIV-1 Envelope
(MDPI, 2020-03-21)
Human immunodeficiency virus (HIV) infection constitutes a major health and social issue worldwide. HIV infects cells by fusing its envelope with the target cell plasma membrane. This process is mediated by the viral Env ...
Modulation of the human disaggregase system by Hsc70-DnaJ associations and small ligands
(2020-07-27)
El sistema desagregasa humano, compuesto por representantes de las familias Hsp70 (Hsc70), Hsp40(DnaJA2 y DnaJB1) y Hsp110 (Apg2) lleva a cabo una gran variedad de funciones cuya finalidad comúnes preservar la proteostasis ...
Atomistic Insights of Calmodulin Gating of Complete Ion Channels
(MDPI, 2020-02-14)
Intracellular calcium is essential for many physiological processes, from neuronal signaling and exocytosis to muscle contraction and bone formation. Ca<sup>2+</sup> signaling from the extracellular medium depends both on ...
How to Inactivate Human Ubiquitin E3 Ligases by Mutation
(Frontiers Media, 2020-02-04)
E3 ubiquitin ligases are the ultimate enzymes involved in the transfer of ubiquitin to substrate proteins, a process that determines the fate of the modified protein. Numerous diseases are caused by defects in the ...
SPANX-A/D protein subfamily plays a key role in nuclear organisation, metabolism and flagellar motility of human spermatozoa
(Nature Publishing Group, 2020-03-27)
Human sperm protein associated with the nucleus on the X chromosome (SPANX) genes encode a protein family (SPANX-A, -B, -C and -D), whose expression is limited to the testis and spermatozoa in normal tissues and to a wide ...
HuR/ELAVL1 drives malignant peripheral nerve sheath tumor growth and metastasis
(The American Society for Clinical Investigation, 2020-07-01)
Cancer cells can develop a strong addiction to discrete molecular regulators, which control the aberrant gene expression programs that drive and maintain the cancer phenotype. Here, we report the identification of the ...
Arachidyl Amido Cholanoic Acid Improves Liver Glucose and Lipid Homeostasis in Nonalcoholic Steatohepatitis Via AMPK and mTOR Regulation
(Baishideng, 2020-09-14)
BACKGROUND Arachidyl amido cholanoic acid (Aramchol) is a potent downregulator of hepatic stearoyl-CoA desaturase 1 (SCD1) protein expression that reduces liver triglycerides and fibrosis in animal models of steatohepatitis. ...
