QQQ (WT/QQQ), PgR_AF1_QQQ
The progesterone receptor (Pgr) is a nuclear steroid receptor that functions as a ligand activated transcription factor regulating gene expression following progesterone hormone binding. The progesterone receptor gene has two distinct promoters and translation start sites in the first exon which produce two isoforms, A and B. PgR_AF1_QQQ knock-in mice carry K461Q, K478Q and R489Q (lysine, lysine, arginine, respectively to glutamine) substitutions in the activation function 1 domain (AF1) of Pgr. Homozygous knock-in mice are viable and fertile. In cell cultures the QQQ mutations result in hyperactivity of the progesterone receptor isoform B (PRB). This strain may be useful for studying the biology of the mammary gland and uterus.PgR_AF1_FFF mice carrying the K461F, K478F and R489F mutations are available as MMRRC Stock No. 067160.
Cryo-recovered strains distributed by the MMRRC at JAX are shipped to the customer from the Pathogen & Opportunistic-Free Animal Room G200 - see https://www.jax.org/jax-mice-and-services/customer-support/customer-service/animal-health/health-status-reports.
Limited quantities of breeder mice (recovered litter) are available from a cryoarchive; recovered litter usually available to ship in 3 to 4 months.
Cryopreserved material may be available upon request, please inquire to csmmrrc@jax.org for more information.
A Commercial License Agreement from the Donor is required for for-profit entities to use this strain. For more information, please contact Rekha Thiagarajan.
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.
A Commercial License Agreement from the Donor is required for for-profit entities to use this strain. For more information, please contact Rekha Thiagarajan
The donor or their institution limits the distribution to non-profit institutions only.
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.
