Symbol:	Capns1tm1Pag
Name:	calpain, small subunit 1; targeted mutation 1, Peter A Greer
MGI ID:	MGI:2179226
Synonyms:	Capn4-
Gene:	Capns1  Location: Chr7:29886361-29898236 bp, - strand  Genetic Position: Chr7, 17.31 cM
Alliance:	Capns1tm1Pag page

Germline Transmission:	Earliest citation of germline transmission: J:74966
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: Disruption of the calpain small subunit gene was achieved by replacing the 3'-terminal half of exon 9 with a PGK-neo cassette. No calpain activity was detected in extracts from homozygous mutant ES cells. Although the large subunit genes were not altered and are transcribed, the resultant proteins are unstable in the absence of the small subunit. (J:74966)
