Deletion of a TATA box results in loss of the corresponding cap sites An insertion of 7 bp between the right TATA box and corresponding cap sites results in a shift of the position of the cap sites so that the original distance of TATA box to cap sites is conserved as much as possible. They are defined by the presence of one or more sequence-specific DNA binding domains falling into several families depending on the type of DNA binding. Transcription factors of plant and animal origin are classified into five major families primarily based on the DNA binding domain they contain.

In genetics an enhancer is a short 501500 bp region of DNA that can be bound by proteins activators to increase the likelihood that transcription of a particular gene will occur These proteins are usually referred to as transcription factors Enhancers are cis-acting. By binding to cis-regulatory elements in a sequence-specific manner transcription factors. Enhancers and Silencers Enhancers have the ability to greatly increase the expression of genes in their vicinity More recently elements have been identified that decrease transcription of neighboring genes and these elements have been called silencers. As such GATA transcription factors represent a group of proteins related solely by their homologous DNA-binding domains Further analysis of this domain.
