Intramembrane proteases identify target proteins in a different way from other proteases.

Biochemical and genetic tests have revealed that a liver protein called NTCP is a functional receptor for hepatitis B and D viruses, which should lead to an improved understanding of the infections caused by these viruses and assist the development of new intervention strategies.

The transcription machinery used to regulate gene expression and self-renewal in human embryonic stem cells is different from that found in other cells.
