Problems solved by technology

While traditional constitutive promoters promote the expression of exogenous genes, they also cause accumulation and waste of target genes in other tissues and organs, and even endanger transgenic individuals
There is no report about the promoter of akirin2 gene in pigs

Abstract

The invention discloses a porcine akirin2 gene promoter and application thereof, the nucleotide sequence of which is shown in SEQ:ID:1. The application of the pig akirin2 gene promoter of the invention in the eukaryotic expression of exogenous genes and transgenic pigs. The present invention determined that the smallest promoter fragment of 200bp has the strongest activity. The invention provides an oligonucleotide primer sequence, a cloning vector, an expression vector, a transformed host, and a method for exogenous protein expression. These provide the basis for further research on the regulation of porcine akirin2 gene in porcine muscle satellite cells and other related cells, and can be used in mammalian cells for foreign protein expression and transgenic research.

Description

technical field [0001] The invention belongs to the technical field of biochemistry, and relates to a porcine akirin2 gene promoter and application thereof. Background technique [0002] In the process of growth and development, organisms can express appropriate protein molecules in a timely manner according to environmental changes and their own needs. This often requires a certain program to regulate gene expression. The expression regulation of eukaryotic genes can be divided into several levels and levels, including DNA level, RNA level and protein level. The RNA level includes transcription initiation, post-transcriptional processing and degradation (RNAi is gene expression regulation at this level). It is generally believed that the regulation of transcription initiation is the key point of gene expression regulation, and the most important and important regulation occurs at the initiation stage of transcription. Eukaryotes affect the activity of RNA polymerase thro...
