Strong/Weak Feature Recognition of Promoters Based on ...

(8 days ago) In this article, we propose a method to recognize the strong/weak property of the promoters based on the nucleotide sequence. To the best of our knowledge, it is the first time to predict the strong/weak property of the promoters. First, position weight matrix (PWM) is used to evaluate the contributions of the nucleotides to the promoter strength.

Plasmids 101: Inducible Promoters - Addgene

(5 days ago) Promoters control the binding of RNA polymerase and transcription factors. Since the promoter region drives transcription of a target gene, it therefore determines the timing of gene expression and largely defines the amount of recombinant protein that will be produced. Many common promoters. like CMV, EF1A, and SV40 promoters, are always active and thus referred to as constitutive promoters.
