We have previously shown that the human genome includes hundreds of genes coding for
putative factors related to the Krüppel zinc-finger protein, which regulates Drosophila …

The blood-brain barrier (BBB) protects the central nervous system (CNS) from harmful blood-borne
factors. Although BBB dysfunction is a hallmark of several neurological disorders, …

The oxygenation of Earth’s surface environment dramatically altered key biological and
geochemical cycles and ultimately ushered in the rise of an ecologically diverse biosphere. …

X-MyT1 is a C2HC-type zinc finger protein that we find to be involved in the primary selection
of neuronal precursor cells in Xenopus. Expression of this gene is positively regulated by …

Neoproterozoic iron formation (NIF) provides evidence for the widespread return of anoxic
and ferruginous basins during a time period associated with major changes in climate, …

The evolution of the global carbon and silicon cycles is thought to have contributed to the
long-term stability of Earth’s climate 1 , 2 – 3 . Many questions remain, however, regarding the …

We have identified in Xenopus and in the mouse two highly related genes, Xiro3 and Irx3
respectively, that encode a Drosophila Iroquois‐related homeobox transcription factor. Xiro3 in …

Sensory fibers of the peripheral nervous system carry sensation from specific sense structures
or use different tissues and organs as receptive fields, and convey this information to the …

Otavi Group is a 1.5–3.5-km-thick epicontinental marine carbonate succession of Neoproterozoic
age, exposed in an 800-km-long Ediacaran−Cambrian fold belt that rims the SW cape …

KRAB zinc‐finger proteins (KRAB‐ZFPs) constitute a large subfamily of ZFPs of the Krüppel
C2H2 type. KRAB (Krüppel‐associated box) is an evolutionarily conserved protein domain …
