Mouse Strain information
APB ID 2444
Added 14/01/2008
Last Edited 10/05/2014
Strain name: C57BL/6-Ptprcltng/AnuApb
Nickname: Lightning ; ENU8B6:045
Strain designation name: C57BL/6-Ptprcltng/Apb
Strain Types Mutant strain
Genetic Details Chemically induced : ENU
Mode of Inheritance Recessive
1.  Affected Gene Name: protein tyrosine phosphatase, receptor type, C  
Chromosome 1
Affected Gene Symbol Ptprc
Protein expression of altered gene: Unknown
Genetic alteration of gene: ENU-induced mutation. ENU induced at T to C transition that results in the amino acid substitution of serine for phenylalanine at position 528 (F528S). Flow cytometry confirmed that protein half-life is reduced.
Location on chromosome (bp): 139959992-140071843 bp, - strand (From Ensembl annotation of NCBI Build 37)

Transcript name: Ptprc-201
bp change: T to C at position 1681 on cDNA
Exon number: 14
Exon ID: ENSMUSE00000595907
cDNA position: 1681
Amino acid change: Phenylalanine to Serine at position 528
Version: NCBI m37, Ensembl build 57
Mutant Construction Technique None
Phenotype Homozygous State Homozygous null mutants have defective T-cell maturation. Decreased CD4-positive T cell number: SP4 thymocytes are reduced compared to in wild-type mice. Abnormal T cell differentiation: * mice exhibit enhanced negative selection compared with wild-type mice. * positive selection of T cell is rescued and single positive thymic subsets compared to in Ptprctm1Mak homozygotes. Decreased double-positive T cell number. Thymus hypoplasia.
