Targeted Allele Detail
Symbol: Pik3r1tm1Tka
Name: phosphoinositide-3-kinase regulatory subunit 1; targeted mutation 1, Takashi Kadowaki
MGI ID: MGI:2149414
Synonyms: p85alpha-, PI3K p85alpha-, Pi3kr1-
Gene: Pik3r1  Location: Chr13:101680563-101768217 bp, - strand  Genetic Position: Chr13, 53.92 cM
Germline Transmission:  Earliest citation of germline transmission: J:52576
Parent Cell Line:  TT2 (ES Cell)
Strain of Origin:  (C57BL/6NCrlj x CBA/JNCrlj)F1
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
Mutation detailsA neomycin cassette replaced the first exon, exon 1A, of the gene. Functional analysis showed that deletion of this exon, which contains the initiation codon, abolished expression of the p85a variant, while not disrupting expression of the p50a or p55a splicing variants. (J:52576)
