Proteolytic Characteristics of Cathepsin D Related to the Recognition and Cleavage of Its Target Proteins

Screening of proteins that were insensitive to CD cleavage in A549-CR cells.
A, The expression of CD in A549 cells was evaluated by Western blotting. The control was transfected with empty vector. B, Comparison of the 2DE images obtained from lysates of A549-CR cells treated with/without CD. The insets represent the typical 2DE images showing spots that were sensitive or insensitive to CD cleavage.
