Functional characterization of hydroxyproline-O-galactosyltransferases for Arabidopsis arabinogalactan-protein synthesis.

BMC plant biology

Kaur D, Held MA, Smith MR, Showalter AM.
PMID: 34903166
BMC Plant Biol. 2021 Dec 13;21(1):590. doi: 10.1186/s12870-021-03362-2.

BACKGROUND: Arabinogalactan-proteins (AGPs) are structurally complex hydroxyproline-rich cell wall glycoproteins ubiquitous in the plant kingdom. AGPs biosynthesis involves a series of post-translational modifications including the addition of type II arabinogalactans to non-contiguous Hyp residues. To date, eight Hyp-galactosyltransferases (Hyp-GALTs;...

Front Cell Dev Biol. 2020 Nov 19;8:581213. doi: 10.3389/fcell.2020.581213. eCollection 2020.

Heparan sulfate proteoglycans (HSPGs) are an evolutionarily ancient subclass of glycoproteins with exquisite structural complexity. They are ubiquitously expressed across tissues and have been found to exert a multitude of effects on cell behavior and the surrounding microenvironment. Evidence...

Physical tuning of galectin-3 signaling.

Proceedings of the National Academy of Sciences of the United States of America

Farhadi SA, Liu R, Becker MW, Phelps EA, Hudalla GA.
PMID: 33941700
Proc Natl Acad Sci U S A. 2021 May 11;118(19). doi: 10.1073/pnas.2024117118.

Galectin-3 (Gal3) exhibits dynamic oligomerization and promiscuous binding, which can lead to concomitant activation of synergistic, antagonistic, or noncooperative signaling pathways that alter cell behavior. Conferring signaling pathway selectivity through mutations in the Gal3-glycan binding interface is challenged by...

Heterologous humoral immunity to human and zoonotic coronaviruses: Aiming for the achilles heel.

Seminars in immunology

Ng KW, Faulkner N, Wrobel AG, Gamblin SJ, Kassiotis G.

Semin Immunol. 2021 Jun;55:101507. doi: 10.1016/j.smim.2021.101507. Epub 2021 Oct 25.

Coronaviruses are evolutionarily successful RNA viruses, common to multiple avian, amphibian and mammalian hosts. Despite their ubiquity and potential impact, knowledge of host immunity to coronaviruses remains incomplete, partly owing to the lack of overt pathogenicity of endemic human...

Mol Oncol. 2021 Dec 02; doi: 10.1002/1878-0261.13147. Epub 2021 Dec 02.

Primary liver cancer, mainly comprising hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC), remains a major global health problem. Although ICC is clinically different from HCC, their molecular differences are still largely unclear. In this study, precision N-glycoproteomic analysis was...

Search for evolutionary roots of land plant arabinogalactan-proteins in charophytes: presence of a rhamnogalactan-protein in Spirogyra pratensis (Zygnematophyceae).

The Plant journal : for cell and molecular biology

PMID: 34767672
Plant J. 2021 Nov 12; doi: 10.1111/tpj.15577. Epub 2021 Nov 12.

Charophyte green algae (CGA) are assigned to be the closest relatives of land plants and therefore enlighten processes in the colonization of terrestrial habitats. For the transition from water to land, plants needed significant physiological and structural changes, as...
