This enables formation of a "class 1, three-residue β-hairpin" structure that is essential for the correct alignment of the APY residues interacting with EphA4.
Indeed, in most species, meiotic recombination is believed to be essential for the proper alignment of homologous chromosomes and their successful segregation at anaphase I (Baker et al. 1976; Hunt and Hassold 2002; Petronczki et al. 2003), and its failure can generate aneuploid gametes and offspring.
This lysine access channel, formed by conserved aromatic residues, is essential for optimal alignment between the methyl-group of SAM and the ε-amine group of the lysine residue required for efficient catalysis [23], [24].
However, mature attachment via the Ndc80 complex is essential for metaphase alignment and anaphase A. The online version of this article (doi 10.1007/s00412-007-0135-3) contains supplementary material, which is available to authorized users.
During meiosis, DSBs are initiated endogenously and are required for meiotic recombination and formation of chiasmata, which are essential for proper alignment and segregation of the chromosomes during the first meiotic division.
While no specific studies addressing this in MSCs are available, information gathered from tendon/ligament fibroblasts strongly suggests that tensile strength and stretch loading are essential for the proper formation and alignment of the tendon or ligament structure [ 125].
Importantly, inhibition of vectorial actin polymerization is essential for proper alignment and contractility of the ventral stress fiber, because continuous elongation of the actin filament bundle from focal adhesions would counteract myosin II-driven shortening of the actomyosin bundle.
In addition, H3T3 phosphorylation by haspin during mitosis is essential for proper alignment of metaphase chromosomes.
This article reviews value-adding activities from target assessment to lead optimization, and highlights the technical and process-related aspects that can be considered essential for performance and alignment within the research organization.
Proper selection of the input parameters for the alignment software is essential to obtain optimum alignment results in chromatographic profiling experiments.
