How can you use “filaments” in a sentence? Here are some example sentences to help you improve your vocabulary:
If this function of profilin is mediated through actin, results from A549 cells suggest that the actin filaments (F-actin) involved in syncytium must be smaller that stress fibers, and not discernible by light microscopy.
The coiled-coil motif has also been identified in a variety of proteins associated with centromeres, centrosomes, the nuclear matrix, and chromatin [ 10 11 12 13 14 ] . TPR, a protein associated with the inner filaments of the nuclear pore complex is an extended coiled-coil protein [ 15 ] . The filamentous structures associated with both the outer and inner surface of the nuclear pore complex suggest that additional unknown coiled-coil proteins might be involved in its assembly.
Among the subset of transcripts that were found to be enriched in the cytoskeleton fraction were several mRNA species, such as those encoding β-actin mRNA and ribosomal protein subunits, that have previously been shown to be cytoskeleton-associated in other cell types [ 13 16 ] . In addition, we identified approximately 20 new members of the cytoskeleton-associated transcriptome, the majority of which encode structural proteins known to interact directly with cytoskeleton filaments, such as spectrin and protein 4.1 (Table 1).
The cytosolic localization of MHCK-B suggests that this enzyme may contribute to a continuous and uniform turnover of myosin II filaments throughout the cell, although it is possible that MHCK-B plays more specific roles in functions yet to be identified.
Perhaps components required for nucleation are de-localized by BDM allowing new polymerization to be re-directed to filopodia, as filopodial extension is thought to be driven by elongation and not nucleation [ 27 ] . The extension of the growth cone itself could result from a similar diversion of actin monomer from nucleation of new filaments to extension of existing filaments.
