Drugs, , 9, These membrane bound enzymes are involved in membrane fusion, cytokine and growth factor shedding, cell migration, muscle development, fertilization, cellular differentiation, cell-cell interactions and cell matrix interaction. The CA mutant is incapable of forming a hybrid swapped dimer between one molecule each of dephosphorylated CA and WT protein, explaining the lag in its phosphorylation kinetics relative to WT. Turunen, G. This is in sharp contrast to the mechanism of intramolecular autophosphorylation put forward by Dodson et al. The desired stereoisomer predominates, in effect reflecting the selectivity of alkylation step caused by the presence of the preexisting adjacent chiral center. It is also one of the most potent HDIs. Clearly, TPX2 triggers a conformational change that results in a catalytically active dimer.
