(GCKIII) proteins using a mechanism analogous to CCM3
... C-terminal region of the GCKIII proteins is a key determinant for CCM3 recognition. The C-terminal tails of MST4 and STK25, when expressed as GST fusion proteins, were sufficient for robust binding to full length CCM3 (Fig. 1C). Interestingly, neither GST kinase tail fusion was able to bind to the i ...
