A transcriptional activator is a protein (transcription factor) that increases transcription of a gene or set of genes. [1] Activators are considered to have positive control over gene expression, as they function to promote gene transcription and, in some cases, are required for the transcription of genes to occur.
Additionally, adding methyl groups to the SHP-1 gene (which reduces the amount of SHP-1 produced) has been linked to lymphoma (a type of blood cancer) . [43] However, SHP-1 may also promote JAK-STAT signalling. A study in 1997 found that SHP-1 potentially allows higher amounts of STAT activation, as opposed to reducing STAT activity. [44]
Early research showed that when one of the Halloween genes was mutated, fly embryos would die before the exoskeleton was created. [6] Mutants in the halloween gene series include the spook , spookier , phantom (or phm ), disembodied (or dib ), shadow (or sad ), and shade genes.
Activator protein 1 (AP-1) is a transcription factor that regulates gene expression in response to a variety of stimuli, including cytokines, growth factors, stress, and bacterial and viral infections. [1] AP-1 controls a number of cellular processes including differentiation, proliferation, and apoptosis. [2]
Transcription activator-like effectors (TALEs) can be engineered to bind to practically any desired DNA sequence, so when combined with a nuclease, DNA can be cut at specific locations. [1] The restriction enzymes can be introduced into cells, for use in gene editing or for genome editing in situ , a technique known as genome editing with ...
