Expression, crystallization and preliminary X-ray studies of the immunoglobulin-like domain 3 of human palladin.

Palladin is a member of the recently discovered palladin/myotilin/myopalladin family, the members of which associate with alpha-actinin. Palladin may play important roles in actin stress-fibre formation, cell adhesion and migration. The immunoglobulin-like domain 3 of human palladin has been overexpressed in Escherichia coli and crystallized suitable for X-ray crystallographic study. Crystals have been obtained using the vapour-diffusion method and belong to space group P2(1). X-ray diffraction data were collected in-house to 1.8 A resolution from a single crystal. The unit-cell parameters are a = 40.9, b = 33.3, c = 34.8 A, beta = 90.3 degrees . One molecule was predicted to be present in the asymmetric unit.
