#Unit 4. Cell Communication and Cell Signaling

In the absence of Delta, 

TM subunit of Notch on the surface of a responding cell is non-covalently associated with its extracellular subunit; extracellular domain is folded

ADAM 10 is a matrix metalloprotease, a member

of a class of metal-containing enzymes that cleave the

extracellular segments of target proteins.
