Transgene description

• Transgene Type: Transgenic (Inserted expressed sequence)
• Mutation: Insertion
• Tg(Myh6-Tnnt2*R92W)1Jcf expresses 1 gene
  Transgene expresses:
  

  Organism	Expressed Gene	Note
  mouse	Tnnt2 (MGI:104597)	Transgene codes for a protein with an arginine to tryptophan mutation.

• Mutation details: This transgene expresses a mouse Tnnt2 gene, with codon 92 mutated to encode a tryptophan instead of the arginine and an 11-amino acid c-myc epitope added to the 5' end of the coding region, under the control of a rat alpha-myosin heavy chain promoter. This line expresses 50% of the total Tnnt2 as the mutant transgenic form. (J:104369)
