Promoter has different meanings depending on the context. Here are the details for each:

  1. Promoter as a person: A promoter is a person or a group of people who come up with an idea of forming a profitable business venture. After the idea is conceived, the promoter(s) work to make it a reality.

  2. Promoter as a team role: In the context of team roles, a Promoter is someone who is outgoing, enthusiastic, and persuasive. They are natural team players who enjoy socializing and building relationships. However, they may have limited attention to detail and can be overly talkative. They may also have a negative response to pressure and may appear superficial.

  3. Promoter as a DNA sequence: In molecular biology, a promoter is a region of DNA where transcription of a gene is initiated. Promoters are a vital component of expression vectors because they control the binding of RNA polymerase. Promoters are about 100-1000 base pairs long and are adjacent and typically upstream (5’) of the sense or coding strand of the transcribed gene. The coding strand is the DNA strand that encodes codons and whose sequence corresponds to the mRNA transcript produced. The antisense strand is referred to as the template strand or non-coding strand as this is the strand that is transcribed by the RNA polymerase. Promoters are controlled by various DNA regulatory sequences including enhancers, boundary elements, insulators, and silencers. There are three main portions that make up a promoter: core promoter, proximal promoter, and distal promoter.

  4. Promoter as a customer category: In the context of Net Promoter Score (NPS), Promoters are customers who loved their experiences and gave scores of 9 and 10. Passives are customers who gave scores of 7 or 8, while Detractors are customers who gave scores of 0 to 6. The goal is to have as many Promoters as possible and to convert Passives and Detractors into Promoters by addressing their concerns and improving their experiences.

  5. Promoter as a chemical: In the context of adhesives, an adhesion promoter is a specialty compound that can react chemically with both the substrate and/or the adhesive. It forms covalent bonds across the interface that are both strong and durable. Adhesion promoter usually consists of molecules with short organic chains with the capability to form primary bonds to either or both the adherend and the bulk adhesive. Adhesion promoter must be considered with regards to the substrate and the adhesive being used.

In conclusion, the term "promoter" can refer to a person, a team role, a DNA sequence, a customer category, or a chemical.
