AAV with mIP2 promoter driven CreERT2
This AAV expresses CreERT2 driven by an islet mIP2 promoter.
This promoter is based on the 1.1 Kb regulatory region of mouse pre-proinsulin II gene, also known as ins2, ins-2, ins-II, insulin-II, or Mody4. It is commonly used for beta cell-specific gene expression in the pancreatic islet. (m)INS2 promoter is also referred as the mIP2 or mIP2 promoter.
A mutated form of estrogen ligand-binding domain (ERT2) that binds to synthetic antagonists (such as tamoxifen or its derivative 4-hydroxy-tamoxifen) but not to circulating estrogen, was fused to the Cre recombinase (Cre) to create CreERT2 (also known as “inducible Cre”). When tamoxifen binds to CreERT2, it induces a conformational change of CreERT2, leading to its nuclear translocation, followed by Cre/Lox-mediated recombination.
Ready-to-use AAV expressing CreERT2 driven by an islet mIP2 promoter. Available in AAV1, AAV2, AAV5, AAV6, AAV8, AAV9, AAV-DJ and other serotypes.
