Multisite phosphorylation of doublecortin by cyclin-dependent kinase 5.

Doublecortin (DCX) is a 40 kDa microtubule-associated protein required for normal neural migration and cortical layering during development. Mutations in the human DCX gene cause a disruption of cortical neuronal migration. Defects in cdk5 (cyclin-dependent kinase 5) also cause defects in neural migration and cortical layering.

A rapid method for detecting extracellular proteinase activity in Cryptococcus neoformans and a survey of 63 isolates.

A rapid method to detect extracellular proteolytic activity around colonies of Cryptococcus neoformans was developed with tannic acid used to complex with residual protein in a solid medium. A survey was conducted with 32 isolates of C. neoformans var.
