Description: Homo sapiens IKAROS family zinc finger 5 (Pegasus) (IKZF5), transcript variant 1, mRNA. RefSeq Summary (NM_001271840): Members of the Ikaros (ZNFN1A1; MIM 603023) family of transcription factors, which includes Pegasus, are expressed in lymphocytes and are implicated in the control of lymphoid development.[supplied by OMIM, Jul 2002]. Transcript (Including UTRs) Position: hg19 chr10:124,750,322-124,768,203 Size: 17,882 Total Exon Count: 5 Strand: - Coding Region Position: hg19 chr10:124,753,296-124,758,141 Size: 4,846 Coding Exon Count: 3
ID:IKZF5_HUMAN DESCRIPTION: RecName: Full=Zinc finger protein Pegasus; AltName: Full=Ikaros family zinc finger protein 5; FUNCTION: DNA-binding protein that binds to the 5'GNNTGTNG-3' core sequence. Transcriptional repressor. SUBUNIT: Self-associates. Interacts with other family members; IKZF1, IKZF2, IKZF3 AND IKZF4. SUBCELLULAR LOCATION: Nucleus (Probable). TISSUE SPECIFICITY: Expressed in brain, heart, skeletal muscle, kidney, and liver. Expressed in the hematopoietic cell lines MOLT- 4, NALM-6 and K-562. Highly expressed in THP-1 and M-07e cell lines, which have characteristics of myeloid and early megakaryocytic cells respectively. DOMAIN: The N-terminal zinc fingers are involved in sequence- specific DNA binding and heterotypic associations with other family members. DOMAIN: C-terminal zinc fingers mediate homodimerization. MISCELLANEOUS: 'Pegasus' was the winged horse in Greek mythology. SIMILARITY: Belongs to the Ikaros C2H2-type zinc-finger protein family. SIMILARITY: Contains 5 C2H2-type zinc fingers.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
