Human-specific gene ARHGAP11B promotes basal progenitor amplification and neocortex expansion Excerpt: “…the C-terminal 47 amino-acids of ARHGAP11B (after lysine-220) constitute not only a unique sequence, resulting from a frameshifting deletion (fig. S10), but also are functionally distinct from their counterpart…
