... one with a denatured mass of 44 kDa, and a smaller product of 40 kDa. Dou- ble alanine mutation of the C-terminal tail extension of s-DAPK-1 (Gly296 ⁄ Arg297) prevented production of the 40 kDa fragment, ... microscopy. These data highlight the existence of an alternative product of the DAPK-1 locus, and suggest that proteolytic removal of the C-terminal tail of s-DAPK-1 i...
