This material is available to academics and nonprofits only.


  • Vector backbone
  • Backbone size w/o insert (bp) 5100
  • Vector type
    Mammalian Expression, Retroviral
  • Selectable markers

Growth in Bacteria

  • Bacterial Resistance(s)
    Ampicillin, 100 μg/mL
  • Growth Temperature
  • Growth Strain(s)
  • Copy number


  • Gene/Insert name
  • Species
    M. musculus (mouse)
  • Mutation
    G525R mutation in the ER. The presence of the G525R point mutation in the cloned ER sequence abrogates its binding to 17β-estradiol while keeping its full sensitivity to the synthetic ligand 4'hydroxytamoxifen (4OHT)
  • Entrez Gene
    Twist1 (a.k.a. M-Twist, Pde, Ska10, Ska<m10Jus>, Twist, bHLHa38, pdt)
  • Tag / Fusion Protein
    • ER hormone binding domain (C terminal on insert)

Cloning Information

  • Cloning method Unknown
  • 5′ sequencing primer pBABE 5'
  • 3′ sequencing primer IRES-R (5'-GCATTCCTTTGGCGAGAG-3')
  • (Common Sequencing Primers)

Depositor Comments

pWZL-Blast-Twist-ER was
generated by replacing the MYC cDNA of pWZL-Blast-DN-MycER
(Littlewood et al., 1995; Watnick et al., 2003) with the mTwist cDNA PCR amplified from pBp-mTwist.
