WebImportantly, phosphomimetic amino acid substitution at S776 can produce neurotoxicity in mice in the absence of a polyQ tract expansion ( Duvick et al., 2010 ). WebCDK-S and DDK phosphorylation of Mer2 S30 and S29 can be bypassed by phosphomimetic amino acids, but break formation under these conditions is still dependent on DDK and CDK-S activity. Coordination between premeiotic S and DSB formation may be achieved by using CDK-S and DDK to initiate both processes.
