Gp2
Name: glycoprotein 2 zymogen granule membrane
Synonyms: 2310037I18Rik
Type: Gene
Species: Mouse
Chromosome: 7
Alteration at locus: Knockout
NCBI: 67133
HGNC: HGNC:4441
Homologene: 133790
Genetic Alterations
A targeting vector was designed to replace exons 2-5, sequence encoding amino acids 1-282, with a neomycin resistance cassette. RT-PCR confirmed the absence of transcript in mutant pancreas.
Genotype Determination
ES Cell Line
R1 derived from (129X1/SvJ x 129S1/Sv)F1-Kitl+
Phenotype
Homozygous: No gross phenotype in the GP2KO. Recent data demonstrated that GP2 is present in intestinal M cells and able to bind Type I fimbriated bacteria. The GP2KO mice were unable to take up Salmonella bacteria into intestinal Peyer's patch. Thus the mouse has become of significant interest in mucosal immunology.

Heterozygous: wild-type
Mammalian Phenotype Terms
Allelic Composition: Gp2tm1Awl/Gp2tm1Awl (Genetic Background: involves: 129S1/Sv * 129X1/SvJ * C57BL/6J )

Strain Development
The targeting vector was electroporated into R1 embryonic stem (ES) cells and the correctly targeted clones injected into pseudopregnant mice. The resultant chimeric mice were bred with C57BL/6 mice. The strain was then backcrossed to C57BL/6 for over 9 generations.
Suggested Control Mice

MMRRC Genetic QC Summary
The MMRRC Centers have developed a genetic QC pipeline using MiniMUGA array genotyping to provide additional information on strain backgrounds for MMRRC congenic and inbred strains. For more information on when data may be available, or to request genotyping for a strain of interest, please contact mmrrc@ucdavis.edu. Older strains may not have this information.

Order Request Information

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 mmrrc@ucdavis.edu for more information.

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.

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.
