Ifrd1 and Ifrd2 were identified using knockout mice as new molecular players regulating via two discrete mechanisms the activity of the transcriptional regulator Dlk1 and thereby affecting adipocyte differentiation.
A biochemical approach using the Wnt pathway as a model system demonstrates a new mechanism for specificity in interconnected signaling networks through scaffold-mediated shielding of bound proteins.
Functional assays using zebrafish reveal that various microbial channelrhodopsins, guanylyl cyclase rhodopsin, and photoactivated adenylyl cyclases function as potent optogenetic tools, effectively controlling neural activity and cardiac function in zebrafish.
Animal G-protein-coupled bistable rhodopsins can regulate Gq- and Gi-mediated signaling in a light-dependent manner in neurons and cardiomyocytes, making them useful for analyzing the roles of GPCR signaling in vivo.
Molecular biology experiments identified a cleaved METTL3, which mediates the METTL3–METTL3 interaction, a prerequisite step for recruitment of WTAP in MTC assembly, controlling m6A deposition and cancer progression.
