Mouse Strain information
APB ID 120
Added 06/02/2006
Last Edited 11/05/2014
Strain name: B6.129P2-Cblbtm1Pngr/AnuApb
Nickname: Cblb KO
Strain designation name: B6.129P2-Cblbtm1Pngr/AnuApb
Strain Types Mutant strain
Genetic Details Targeted knockout
Mode of Inheritance Recessive
1.  Affected Gene Name: Casitas B-lineage lymphoma b  
Chromosome 16
Affected Gene Symbol Cblb
Protein expression of altered gene: Nil
Genetic alteration of gene: A neomycin cassette replaced the region encoding a portion of the tyrosine kinase-binding and RING finger domains, corresponding to amino acids 300 through 340 of the encoded protein. Western blot analysis showed an absence of protein expression in lymph nodes and splenocytes from homozygous mice.
Location on chromosome (bp): 52031662-52208160 bp, + strand (From NCBI annotation of NCBI Build 37)
