Pck1tm1.1Mgn

These mice may be used to study tissue-specific functions of phosphoenolpyruvate carboxykinase  (Pck1).  This enzyme is essential for gluconeogenesis and also is important for regulating anapleurosis/catapleurosis of TCA cycle intermediates.  By generating mice that are homozygous for the pck{lox} allele and that contain a tissue-specific Cre transgene Pck1 can be deleted from various sites.

Genetic Alteration

Mutation #1: Targeted Mutagenesis
Type of AlleleConditional Null
Targeted GeneName: phosphoenolpyruvate carboxykinase 1
Symbol: Pck1
NCBI: 18534
Allele Name: targeted mutation 1.1, Mark A Magnuson
Symbol: Pck1tm1.1Mgn
MGI: MGI:2449283
Description of Targeting Vector

A gene targeting strategy was used to flank exons 4 and 5 in the Pck1 gene with two tandomly-oriented loxP sites. DNA PCR utilizing primers 5'-AATGTTCTCTGCAAGTCCTGGTG-3' and 5'-TCTGTCAGTTCAATACCAATCT-3' amplify a 616 bp pckloxband and a 518 bp wild type band. Homozygous Pcklox/lox animals are viable. Pck1 activity and protein content in liver and kidney do not differ from wild type. Heterozygous animals are also viable and do not differ from the wild type.
