Romet-Lemonne/Jegou Lab – Regulation of branched versus linear Arp2/3-generated actin filaments

Actualités, Les dernières publications21 mars 2023
L’équipe Romet-Lemonne/Jegou vient de publier un nouvel article dans the EMBO Journal. Regulation of branched versus linear Arp2/3-generated actin filaments Abstract Activation of the Arp2/3 complex by VCA-motif-bearing actin nucleation-promoting factors results in the formation of “daughter” actin filaments branching off the sides of pre-existing “mother” filaments. Alternatively, when stimulated by SPIN90, Arp2/3 directly nucleates “linear” actin…

Greenberg Lab – Conservation and divergence of canonical and non-canonical imprinting in murids

Actualités, Les dernières publications15 mars 2023
L'équipe Greenberg vient de publier dans Genome Biology. Conservation and divergence of canonical and non-canonical imprinting in murids Abstract Background Genomic imprinting affects gene expression in a parent-of-origin manner and has a profound impact on complex traits including growth and behavior. While the rat is widely used to model human pathophysiology, few imprinted genes have been…
