Question: What is the phenomenon of gene kissing?

Context: This positioning can also result in the clustering of genes with similar expression patterns, a phenomenon sometimes called "gene kissing."
We speculate that our findings might provide insight into other types of gene kissing, some of which also require cis-acting DNA sequences and trans-acting proteins.
The imposition at a distance of new chromatin structures with regulatory impact can occur in cis as well as in trans, and is examined as intrachromosomally spreading teleregulation and interchromosomal "gene kissing".
Instances of 2 different alleles touching each other were found in 20-47% of nuclei depending on the tissue. The frequency of such "kissing" events was not significantly different in cells expressing a high proportion of the Hox clusters when compared to cells expressing none or only a few Hox genes
We found that the HoxB and HoxC clusters, which are located in gene-rich regions, were involved more frequently in gene kissing in embryonic nuclei.
This positioning can also result in the clustering of genes with similar expression patterns, a phenomenon sometimes called "gene kissing."

genomes are spatially organized on many levels and the positioning of genes within the nucleus contributes to their proper expression this positioning can also result in the clustering of genes with similar expression patterns a phenomenon sometimes called gene kissing we have found that yeast genes are targeted to the nuclear periphery through interaction of the nuclear pore complex with small cis acting dna zip codes in their promoters our recent study demonstrated that genes with the same zip codes cluster together at the nuclear periphery the zip codes were necessary and sufficient to induce interchromosomal clustering finally we identified a transcription factor put3 that binds to the grs i zip code put3 binds to grs i and is required for both grs i dependent positioning at the nuclear periphery and interchromosomal clustering of grs i targeted genes we speculate that our findings might provide insight into other types of gene kissing some of which also require cis acting dna sequences and trans acting proteins.
