LINE-1-encoded ORF1p is widely expressed in neurons, increases with age, and engages neuron-specific protein partners, revealing a dynamic role for retrotransposons in brain physiology and aging.
A neutrality index identifies mox-YG as a minimally cytotoxic protein, enabling ultra-high expression and uncovering key physiological consequences of protein burden.
Sex-biased gene expression in the body organs evolves rapidly, supporting a mosaic model of maleness and femaleness across tissues and thus challenging binary views of sex characteristics in mammals.
Trans-species polymorphism at primate Major Histocompatibility Complex genes is old, especially in the 'classical' genes, while rapidly-evolving regions of each gene correspond with proteins' functional domains.
