The unfolded protein response sensor/transducer IRE1-mediated splicing of XBP1 mRNA encoding its active downstream transcription factor to maintain the homeostasis of the endoplasmic reticulum is sufficient for growth and development of medaka fish.
Mice deficient in the TRPM6 channel suffer from impaired prenatal development, shortened lifespan, growth deficit and disturbed energy balance due to a defect in epithelial Mg2+ uptake, thus highlighting a pivotal role of TRPM6 in organismal Mg2+ homeostasis.
The proteins Bax and Bak, which increase the permeability of the mitochondrial membrane during apoptosis, are also crucial for generating a mitochondrial membrane pore that is specifically involved in necrosis.
A novel GABAAR assembly pathway that promotes synaptic inhibition is established and provides a molecular explanation for how GABAARs with distinct subunit compositions display distinct subcellular distributions.
Lineage analysis reveals that cardiac neural crest contributes to cardiomyocytes across vertebrates and consistent with this, the neural crest gene regulatory program is reactivated upon heart regeneration in zebrafish.
Histone-lysine N-methyltransferase SETD3 (NP_115609.2) was identified as the actin-specific histidine N-methyltransferase, an enzyme catalyzing the extremely well-conserved methylation of H73 in β-actin.
