That means the KIFC1-like protein moving towards the caudal end of spermatid will transmit the motor-generated force to the nucleus and, instead of bringing about translocation in position, facilitate mechanical rearrangement of the nuclear lamina and other endonuclear components and eventually elongation and condensation of the nucleus.
This study presents phylogenetically-robust evidence that sperm competition in mammals favours an increase in the size of all sperm components and an elongation of the head, which result in faster swimming speeds.
For both methods, the gene ontology (GO) term analysis was very similar and included enrichment for ribosome components, translation initiation and elongation factors, protein targeting/sorting genes (co-translational process, and post-translational translocation), and RNA metabolism genes (Tables S2, S3, S4).
Studies have shown that elongin C has dual functions as an E3 ubiquitin ligase component and a transcription elongation factor (reviewed in Kim & Kaelin, 2003; Shilatifard et al., 2003).
Phosphorylation of ten translational factors, including ribosomal subunits and translation initiation and elongation components, were identified in our analysis.
Within the following 9 hours of late germination phase, genes encoding many metabolic pathway enzymes and cellular components including amino acid and nucleotide synthesis, protein degradation, chromatin remodeling and cell division pathways are preferentially up-regulated to provide nutrient and cellular components for cell division and elongation.
Further experiments clarified that the spontaneous E. coli flocs were proteinous, and elongation factor Ts (Tsf) was the main component.
It has been described that the basal machinery of P. falciparum is well conserved with a similar number of components accountable for mRNA initiation and elongation of transcription when compared to other eukaryotes [ 41].
Mass spectroscopy revealed that other components of the actin cytoskeleton co-purified with these mRNAs, namely actin, tubulin, and elongation factor 1α.
When significant (MR, IM, ML, UHML, UI, and elongation), this interaction component was always strongly inferior to the genotypic (RIL) effect (Table 3), confirming data from the literature and indicating that the genetic influence on major fiber characteristics was generally greater than non-genetic influences (reviewed in [ 5]).
