Genetic Alterations

CRISPR/Cas9 gene editing was used to place Lox p sites in sequences flanking exon 8 (introns 8 and 9, away from sequences implicated in splicing). Diagnostic BamH1 and Ecor1 restriction sites were also inserted into intron 8. When crossed with cre recombinase-expressing mice, exon 9 is deleted in cre-expressing tissues resulting in the inability to express the beta and gamma isoforms of SH2B1. Only the alpha and delta isoforms of SH2B1 are able to be expressed.

Phenotype
The phenotype of the floxed mice is the same as wild-type mice in terms of weight and adiposity (gonadal adipose tissue weight). The heterozygous and homozygous mice breed normally. If the mice are crossed with syn1-cre mice, the beta and gamma isoforms are no longer expressed in neurons. These mice did not have altered weight or adipose tissue weight. However, if the beta and gamma isoforms are no longer expressed in any tissue in mice, then the male (but not female) SH2B1 beta/gamma KO mice exhibit increased weight, food intake and adiposity. Insulin and glucose tolerance were normal in both male and female mice. However, fed insulin levels were elevated in the female homozygous SH2B1 beta/gamma KO mice. The latter results imply that knocking out the beta and gamma isoforms of SH2B1 from some tissues will result in an obese phenotype.

Distribution of this strain requires submission of the MMRRC Conditions of Use (COU). A link to the COU web form will be provided via email after an order has been placed; the form should be completed then or the email forwarded to your institutional official for completion.

Additional charges may apply for any special requests. Shipping costs are in addition to the basic distribution/resuscitation fees. Information on shipping costs and any additional charges will be provided by the supplying MMRRC facility.

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.
