WebBy combining single-nuclei ATAC-seq data with single-nucleus transcriptomics data, it is possible to systematically map gene cis-regulatory elements (CREs) for each cell type and elucidate the gene-regulatory landscape of the retina. These putative regulatory elements will be useful for identifying and prioritizing non-coding mutations ... Trans-regulatory elements work through an intermolecular interaction between two different molecules and so are said to be "acting in trans". For example (1) a transcribed and translated transcription factor protein derived from the trans-regulatory element; and a (2) DNA regulatory element that is adjacent to the regulated gene. This is in contrast to cis-regulatory elements that work through an intramolecular interaction between different parts of the same molecule: (1) a ge… haines library haines alaska
