sentence: According to the above-mentioned studies , the CaaX motif of farnesylated lamins and potentially of Kugelkern seems to be sufficient for inducing NM growth , because even the chimeric construct GFP-NLS-CaaX , where the rod domain of lamin is absent , shows activity on the NM.In contrast to the filament forming N-terminal part of lamin that has been extensively studied ( Wiesel et al ., 2008 ; Ben-Harush et al ., 2009 ; Kapinos et al ., 2010 ) , the analysis of the C-terminal part has been rather limited .
