Identifying sources of D-serine in Caenorhabditis elegans and their impact on behavior [PDF]

open access: yes, 2021
Free D-serine (D-Ser) is a potent co-agonist of the N-methyl-D-aspartate receptor (NMDAR) in glutamate neurotransmission and regulates NMDAR functions in the nervous system.

Targeting one-carbon metabolism requires mTOR inhibition: a new therapeutic approach in osteosarcoma

open access: yesMolecular & Cellular Oncology, 2021
The rate-limiting enzyme of serine biosynthesis, 3-phosphoglycerate dehydrogenase (PHGDH), contributes to rapid growth and proliferation when it is overexpressed in cancer.

Serine-Modified Au@Cu2O Core–Shell Nanoparticles for Catalysis-Mediated Colorimetric Detection of Small Molecules

open access: yes, 2023
3,3′,5,5′-Tetramethylbenzidine (TMB)-based catalysis-mediated colorimetric analysis for the detection of small molecules has poor specificity. In this study, well-prepared Au@Cu2O core–shell nanocatalysts (NCs) were fabricated that have excellent ...

Serine-based surfactants as effective antimicrobial agents against multiresistant bacteria

open access: yes, 2022
The antimicrobial activity of two serine derived gemini cationic surfactants, amide (12Ser)2CON12 and ester (12Ser)2COO12, was tested using sensitive, E. coli ATCC 25922 and S. aureus ATCC 6538, and resistant, E. coli CTX M2, E.

tPA promotes ADAMTS-4-induced CSPG degradation, thereby enhancing neuroplasticity following spinal cord injury

open access: yesNeurobiology of Disease, 2014
Although tissue plasminogen activator (tPA) is known to promote neuronal remodeling in the CNS, no mechanism of how this plastic function takes place has been reported so far.

Mapping the ACE2 binding site on the SARS-CoV-2 spike protein S1: molecular recognition pattern [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2020
Coronavirus SARS-CoV-2 enters the host cell via binding with the angiotensin-converting enzyme 2 (ACE2), and here we used computational modelling to study the molecular recognition pattern of this interaction.

Serine-Selective Bioconjugation

open access: yesJournal of the American Chemical Society, 2020
The first general method for the rapid, chemoselective, and modular functionalization of serine residues in native polypeptides is reported. Using a reagent platform based on P(V) oxidation state, this redox-economic approach can be used to append nearly any kind of cargo onto serine generating a stable, benign, and hydrophilic phosphorothioate linkage.

Seprase: An overview of an important matrix serine protease [PDF]

open access: yes, 2008
Seprase or Fibroblast Activation Protein (FAP) is an integral membrane serine peptidase, which has been shown to have gelatinase activity. Seprase has a dual function in tumour progression.
