Reporter genes are genes that enable the detection or measurement of gene expression. They can be fused to regulatory sequences or genes of interest to report expression location or levels. Reporter genes include genes that code for fluorescent protein and enzymes that convert invisible substrates to luminescent or coloured products.
AtGBPL3 is a dynamin-related GTPase that functions in mitotic nuclear envelope formation. It interacts with lamina components to mediate nuclear morphogenesis and transcriptional repression during interphase.
This protocol describes the use of Retro-Cascorder to make temporally resolved transcriptional recordings in Escherichia coli DNA, using a retron reverse transcriptase to store transcriptional events in a unidirectionally expanding CRISPR array via acquisition by CRISPR–Cas integrases.
Detecting distinct glycans within heterogeneous mixtures is hindered by glycan structural complexity and diversity. Here the authors exploit the ability of gut microbes to sense different glycan structures in order to develop quantitative glycan biosensors by coupling bacterial detection machinery to an optimised luciferase reporter.
