Symbol:	Hcn2tm1Ldw
Name:	hyperpolarization-activated, cyclic nucleotide-gated K+ 2; targeted mutation 1, Andreas Ludwig
MGI ID:	MGI:2449917
Synonyms:	HCN2-
Gene:	Hcn2  Location: Chr10:79552468-79571942 bp, + strand  Genetic Position: Chr10, 39.72 cM, cytoband C1
Alliance:	Hcn2tm1Ldw page

Germline Transmission:	Earliest citation of germline transmission: J:81398
Parent Cell Line:	R1 (ES Cell)
Strain of Origin:	(129X1/SvJ x 129S1/Sv)F1-Kitl+

Allele Type:    Targeted (Null/knockout) Mutations:    Insertion, Intragenic deletion   Mutation details: A floxed neo cassette and a single loxP site flanking exons 2 and 3 were introduced via homologous recombination. The floxed neo cassette and exons 2 and 3 were removed by transient expression of cre recombinase in correctly targeted cells, resulting in deletion of sequences encoding 5 of the 6 transmembrane segments of the Hcn2 channel as well as part of the pore. Absence of gene expression was confirmed by Northern and Western blot analysis of brain extracts from homozygous mutant animals. (J:81398)
