Targeted Allele Detail
Symbol: Nrp1tm1Ddg
Name: neuropilin 1; targeted mutation 1, David D Ginty
MGI ID: MGI:3512099
Synonyms: npn-1Sema-
Gene: Nrp1  Location: Chr8:128358604-128503363 bp, + strand  Genetic Position: Chr8, 75.78 cM, cytoband E
Germline Transmission:  Earliest citation of germline transmission: J:93799
Parent Cell Line:  GK129 (ES Cell)
Strain of Origin:  129P2/OlaHsd
Allele Type:    Targeted
Mutation:    Insertion
Mutation detailsExon 2 was replaced with a mutated exon 2 encoding 7 amino acid substitutions (H46E, S47A, S51A, E52R, K53D, D79K, R80E) in three regions of the amino-terminal CUB domain, and a loxP site flanked neomycin resistance gene cassette was inserted into intron 1. The neo cassette was removed through subsequent cre-mediated recombination. Mutation of these sites was shown to abolish Sema3 family binding but not VEGF binding. Immunohistochemistry showed that homozygotes express normal levels of protein. (J:93799)
