Furthermore, the atomic-resolution HAADF images and HRXRD reciprocal space mappings indicate that interfaces between different layers in MQWs are pseudomorphic.
It is distinct from other forms of oligomerization in that the binding interface is formed by reciprocal exchange of polypeptide segments.
Frequently, expression of Eph receptors and ephrins is reciprocal and, through repulsive interactions at interfaces, organizes positioning and/or movement of cells including the restriction of migrating neural crest cells (NCC) to specific embryonic territories [Wilkinson, 2001].
As a point of comparison, we investigated a putative α-expansin, unigene 11, which showed a reciprocal pattern of high expression in the interface transcriptome of T. versicolor grown on M. truncatula.
Despite some variation in method and interpretation (e.g., Gomulkiewicz et al. 2007; Hanifin et al. 2008), matching and mismatching in the phenotypic interface may roughly represent the potential for reciprocal selection.
Another reciprocal change involves H163 of human Runx1 RD, which interfaces with T62 and F17 in CBFβ; the corresponding residues in Nematostella are C131 (in RD) and S62 and M17 (in CBFβ), respectively.
This method requires only one selected area diffraction pattern on the edge-on interface and a three-dimensional simulation of the reciprocal lattices of both structures.
NK1 crystallises as a head-to-tail dimer with an extensive inter-protomeric interface resulting from contacts between the two short interdomain linkers and reciprocal contacts between the N and K1 domains.
One of these interactions is related to the temperature jump and heat flux through the interface of different materials, known as thermal contact resistance, or its reciprocal, the thermal contact conductance.
However, up to date it is an unsolved question if reciprocal exchange of morphogenetic information occurs exclusively via free diffusion through this interstitial interface or if also factors are involved bound on extracellular matrix.
