1 When indicated as verified ("YES"), then please note that information presented is to the best of our knowledge correct and up-to-date at the time of verification at the MMRRC Distribution Center; however, this information is subject to change due to breeding, maintenance, and other actions on the mouse strain at the MMRRC Distribution Center; direct any questions on this table to the MMRRC Distribution Center for this mouse stain.

2 If verification has not been performed (as indicated by "NO"), investigators may request specific verification testing for a fee. Requests should be submitted directly to the MMRRC Distribution Center assigned to the management, archiving, and distribution of the strain. A full listing of available testing and analytical services is available at https://www.mmrrc.org/about/services.php.

3 This information may or may not apply to each individual engineered allele (e.g., Cre, FlpO) present in the strain.

Genetic Alterations
MYL2-WT transgenic mice harbor human wildtype MYL2 cDNA driven by the mouse Myh6 promoter. This is a control mouse line to the MYL2-D94A (RRID:MMRRC_075944-JAX) and MYL2-D166V (RRID:MMRRC_075945-JAX) mutant transgenic lines and may be useful when studying familial dilated and hypertrophic cardiomyopathies.
ES Cell Line
Not applicable
Phenotype
Ventricular myosin light chain 2, encoded by the Myl2 (myosin, light polypeptide 2, regulatory, cardiac, slow) gene, is essential in vertebrate smooth muscle contraction and has a regulatory role in striated slow twitch muscle contraction. Mutations in this gene have been associated with hypertrophic and dilated cardiomyopathies. These MYL2-WT transgenic mice harbor human wildtype MYL2 cDNA driven by the mouse myosin, heavy polypeptide 6, cardiac muscle, alpha (Myh6) promoter.

Hemizygous mice are viable and fertile. The donating laboratory has not evaluated homozygous mice. MYL2-WT mice do not demonstrate any significant cardiac differences compared to non-transgenic littermates. These mice may be useful controls to the MYL2-D94A (RRID:MMRRC_075944-JAX) and MYL2-D166V (RRID:MMRRC_075945-JAX) mutant transgenic lines when studying familial dilated and hypertrophic cardiomyopathies.

To request gene-specific and other genotyping services for a strain, please contact the distribution MMRRC Center for more information.

Background Genetic Quality:

The MMRRC has developed a Genetic Quality Control pipeline using the MiniMUGA array to provide additional information to identify and validate genetic backgrounds of MMRRC strains. For more information on whether genetic background data is available, please contact MMRRC_GeneticQC@med.unc.edu. Note: that MiniMUGA genetic background data is not available on all strains, but can be ordered if desired.

Strain Development
The MYL2-WT transgene was generated using human myosin, light polypeptide 2, regulatory, cardiac, slow (MYL2) cDNA driven by the mouse myosin, heavy polypeptide 6, cardiac muscle, alpha (Myh6) promoter. The final transgene construct included approximately 5.5kb of the mouse Myh6 promoter, including the first two exons and part of the third, followed by human MYL2-WT cDNA (~498bp) and a 623bp 3' untranslated region (UTR) from the human growth hormone (hGH) transcript. The purified linearized DNA was microinjected into the pronuclei of fertilized mouse oocytes obtained from (C57BL/6XSJL)F1 matings. Two founder lines were generated, founder line L2 was further expanded. The donating laboratory has indicated that the transgene copy number and integration site are not known. The MYL2-WT transgenic colony was maintained by crossing hemizygous mice to B6SJLF1/J mice. Upon arrival at The Jackson Laboratory, sperm was cryopreserved. To establish a live colony, an aliquot of frozen sperm was used to fertilize B6SJLF1/J oocytes.

1 The distribution fee covers the expense of rederiving mice from a live mouse; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.

2 An aliquot contains a sufficient number of embryos (in one or more vials or straws and based on the transfer success rate of the MMRRC facility) to transfer into one to three recipients. The MMRRC makes no guarantee concerning embryo transfer success experienced in the recipient investigator's laboratory. Neither gender nor genotype ratios are guaranteed.

3 An aliquot is one straw or vial with sufficient sperm to recover at least one litter of mice, as per provided protocols, when performed at the MMRRC facility. The MMRRC makes no guarantee concerning the success of these procedures when performed outside the MMRRC facilities.

4 The distribution fee covers the expense of resuscitating mice from the cryo-archive; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.
