![عکس صفحه اول مقاله: Giardia lamblia Nek1 and Nek2 kinases affect mitosis and excystation Giardia lamblia Nek1 and Nek2 kinases affect mitosis and excystation](/preview/png/2436257.png)
The NIMA-related serine/threonine kinases (Neks) function in the cell cycle and regulate ciliary and flagellar length. The Giardia lamblia genome encodes 198 Neks, of which 56 are predicted to be active. Here we believe that we report the first functional analysis of two G. lamblia Neks. The GlNek1 and GlNek2 kinase domains share 57% and 43% identity to the kinase domains of human Nek1 and Nek2, respectively. Both GlNeks are active in vitro, have dynamic relocalisation during the cell cycle, and are expressed throughout the life cycle, with GlNek1 being upregulated in cysts. Over-expression of inactive GlNek1 delays disassembly of the parental attachment disc and cytokinesis, whilst over-expression of either wild type GlNek1 or inactive mutant GlNek2 inhibits excystation.
