Cleavage of Histone 3 by Cathepsin D in the Involuting Mammary Gland
Theoretically predicted cleavage sites are also indicated (red in A). The in vitro cleavage of the recombinant H3.3 protein by ID2-derived mCatD and CatL is also indicated in Fig. 4B, with the total cell lysate of the mouse mammary gland at involution day 2 included as reference. The NH2 terminal sequence of H3 cleavage product (marked by *) is depicted in C.
