Description: paternally expressed 3 [Source:HGNC Symbol;Acc:HGNC:8826]
Entrez Summary In human, ZIM2 and PEG3 are treated as two distinct genes though they share multiple 5' exons and a common promoter and both genes are paternally expressed (PMID:15203203). Alternative splicing events connect their shared 5' exons either with the remaining 4 exons unique to ZIM2, or with the remaining 2 exons unique to PEG3. In contrast, in other mammals ZIM2 does not undergo imprinting and, in mouse, cow, and likely other mammals as well, the ZIM2 and PEG3 genes do not share exons. Human PEG3 protein belongs to the Kruppel C2H2-type zinc finger protein family. PEG3 may play a role in cell proliferation and p53-mediated apoptosis. PEG3 has also shown tumor suppressor activity and tumorigenesis in glioma and ovarian cells. Alternative splicing of this PEG3 gene results in multiple transcript variants encoding distinct isoforms.

Source Annotation
TF-CAT classification No
Vaquerizas 2009 TF classification
"a" Has direct evidence of TF function;
"b" Has evidence for an orthologous TF;
"c" contains likely DBDs, but has no functional evidence;
"x" is an unlikely TF such as predicted gene, genes with likely non-specific DBDs or that have function outside transcription;
"other" category contains proteins without clear DBDs they curated from external sources.
CisBP considers it as a TF? Yes
TFclass considers it as a TF? Yes

Initial Assessment
1a1 Protein has a high confidence PWM (HT-SELEX, PBM or B1H model) or there is a crystal structure that supports sequence specific DNA binding;
1a2 There is high confidence data for a close ortholog (as defined in CisBP);
2a1 There is lower confidence direct evidence, such as a Jaspar, Hocomoco or Transfac model;
2a2 There is lower confidence evidence for an close ortholog;
3a There is decent circumstantial evidence for its role as a TF or not;
4a Two or more datasets predict it as a TF;
5a One of the source datasets predicts is as a TF
4a, two or more datasets predict it as a TF
TF has conditional DNA-binding requirements
