Ptf1a{YFP} mice may be used to visualize yellow flurrescent protein (YFP) expression from the ptf1a allele.  Ptf1a is expressed in pancreatic buds beginning at E9.5 and plays a vital role in the growth and lineage specification of pancreatic multipotent progenitor cells (MPCs).  Ptf1a is also expressed in the neuronal precursors of the cerebellum, spinal cord, and retina where it also performs fate determining roles.

Genetic Alteration

Mutation #1: RMCE Targeted Mutagenesis
Type of AlleleGene Replacement
Targeted GeneName: pancreas specific transcription factor, 1a
Symbol: Ptf1a
NCBI: 1328312
Allele Name: targeted mutation 1.1
Symbol: ptf1atm1.1(YFP)
MGI: MGI:3691484
Description of Targeting Vector

Coding sequences for citrine, a yellow fluorescent protein, were inserted into exon 1 of the Ptf1a locus. Briefly, the endogenous NotI site in exon 1 of Ptf1a was mutated to a FseI site. Citrine DNA was PCR amplified with a 5' Kozak consensus sequence and cloned in between the unique FseI and MluI sites within exon 1 of Ptf1a which replaces sequences containing 5' UTR as well as a portion of the Ptf1a coding region.

Strain Type Mixed
Chimera/Founder Genetic Background 129S6/SvEvTac
Current Genetic Background CD-1
Number of Generations Backcrossed 8
Strain Description

After achieving germline transmission, mice carrying the ptf1aYFP+hygroR allele were mated to a FlpE-expressing transgenic line in order to remove the FRT flanked hygroR cassette.  Ptf1aYFP mice were then backcrossed to CD-1 outbred mice for eight generationss.
