Grk1tm1.1Elrw
Name: G protein-coupled receptor kinase 1; targeted mutation 1.1, Ellen R Weiss
Synonyms: GRK1-Ser21A
Type: Allele
Species: Mus musculus (mouse)
Chromosome: 8
Alteration at locus: Knock-In
Grk1
Name: G protein-coupled receptor kinase 1
Synonyms: RK, Rhok
Type: Gene
Species: Mouse
Chromosome: 8
NCBI: 24013
Homologene: 2197
Genetic Alterations
Serine, codon 21 (AGT) in exon 1, was changed to alanine (p.S21A) and a loxP site flanked neomycin resistance gene cassette was inserted into intron 1. The neo cassette was removed through subsequent Cre-mediated recombination. The mutation prevents phosphorylation of the affected residue in the encoded peptide.

Genotype Determination
  • Genotyping Protocol(s)
  • Center protocol and contact for technical support will be shipped with mice.
  • ES Cell Line
    C57BL/6N-PRX-B6N #1 derived from C57BL/6N
    Phenotype
    Rod dark adaptation following exposure to bright light was significantly delayed. This suggests that the increased activity of the kinase results in enhanced rhodopsin phosphorylation and thus delays its regeneration.

    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
    GRK1-S21A knock-in mice were generated by homologous recombination in C57BL/6N ES cells. A gene targeting vector including a mutation of serine 21 to alanine in exon 1 and a loxP-flanked PGK-Neomycin resistance cassette in intron 1 was constructed and electroporated into C57BL/6N-PRX-B6N ES cells. Correctly targeted cells were injected into C57BL/6-albino blastocysts for chimera formation. Chimeras were mated to C57BL/6-albino animals for germline transmission of the targeted allele. Positive mice were mated to B6.C-Tg(CMV-cre)1Cgn/J, to remove the floxed neo cassette. The resulting line containing the S21A mutation was backcrossed to homozygosity and crossed into C57BL/6J mice to ensure the absence of the rd8 mutation.

    Disclaimer: If MMRRC Strain Genetic Quality Control (GQC; based on MiniMUGA genotyping and analysis) has been completed for this strain, the information might differ from the genetic background information provided by the submitter. MiniMUGA genetic analysis is done on a strain's tissue samples taken when archived by or ordered from the assigned MMRRC Center.

    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.
