- gap junction
A cell-cell junction composed of pannexins or innexins and connexins, two different families of channel-forming proteins.
- obsolete positive regulation of terminal gap gene transcription
OBSOLETE. The activation of genes encoding transcription factors at the anterior and posterior ends of an insect embryo by a combination of maternal regulatory signals and interactions among themselves; exemplified by the activation of expression of the Drosophila tailless and huckebein genes.
- obsolete positive regulation of central gap gene transcription
OBSOLETE. The activation of genes encoding transcription factors in the central region of an insect embryo by a combination of maternal regulatory signals and interactions among themselves; exemplified by the activation of expression of the Drosophila Kruppel gene by the hunchback and bicoid gene products.
- obsolete positive regulation of posterior gap gene transcription
OBSOLETE. The activation of genes encoding transcription factors in the posterior region of an insect embryo by a combination of maternal regulatory signals and interactions among themselves; exemplified by the activation of expression of the Drosophila knirps gene.
- gap junction assembly
Assembly of gap junctions, which are found in most animal tissues, and serve as direct connections between the cytoplasms of adjacent cells. They provide open channels through the plasma membrane, allowing ions and small molecules (less than approximately a thousand daltons) to diffuse freely between neighboring cells, but preventing the passage of proteins and nucleic acids.
