Smn1^tm1Msd
Targeted Allele Detail

Summary

• Symbol: Smn1^tm1Msd
• Name: survival motor neuron 1; targeted mutation 1, Michael Sendtner
• MGI ID: MGI:2183946
• Synonyms: SMN^-
• Gene: Smn1 Location: Chr13:100261360-100274198 bp, + strand Genetic Position: Chr13, 52.99 cM, cytoband D1/D2.1
• Alliance: Smn1^tm1Msd page

Mutation origin

• Germline Transmission: Earliest citation of germline transmission: J:42813
• Parent Cell Line: E14TG2aIV (ES Cell)
• Strain of Origin: 129P2/OlaHsd

Mutation description

• Allele Type: Targeted (Null/knockout, Reporter)
• Mutation: Insertion
• Mutation details: A lacZ-neo cassette was inserted into exon 2 by homologous recombination resulting in an in-frame fusion of lacZ to exon 2. Homozygous mutant embryos were identified up to 80 hours post coitum. The expression of the lacZ gene in tissues where Smn is normally expressed was noted. (J:42813)
