ID:ZEP1_HUMAN DESCRIPTION: RecName: Full=Zinc finger protein 40; AltName: Full=Cirhin interaction protein; Short=CIRIP; AltName: Full=Gate keeper of apoptosis-activating protein; Short=GAAP; AltName: Full=Human immunodeficiency virus type I enhancer-binding protein 1; Short=HIV-EP1; AltName: Full=Major histocompatibility complex-binding protein 1; Short=MBP-1; AltName: Full=Positive regulatory domain II-binding factor 1; Short=PRDII-BF1; FUNCTION: This protein specifically binds to the DNA sequence 5'- GGGACTTTCC-3' which is found in the enhancer elements of numerous viral promoters such as those of SV40, CMV, or HIV-1. In addition, related sequences are found in the enhancer elements of a number of cellular promoters, including those of the class I MHC, interleukin-2 receptor, and interferon-beta genes. It may act in T-cell activation. Involved in activating HIV-1 gene expression. Isoform 2 and isoform 3 also bind to the IPCS (IRF1 and p53 common sequence) DNA sequence in the promoter region of interferon regulatory factor 1 and p53 genes and are involved in transcription regulation of these genes. Isoform 2 does not activate HIV-1 gene expression. Isoform 2 and isoform 3 may be involved in apoptosis. SUBUNIT: Interacts with CIRH1A. INTERACTION: P54253:ATXN1; NbExp=6; IntAct=EBI-722264, EBI-930964; O00555:CACNA1A; NbExp=2; IntAct=EBI-722264, EBI-766279; SUBCELLULAR LOCATION: Isoform 1: Nucleus. SUBCELLULAR LOCATION: Isoform 2: Cytoplasm. Nucleus. SUBCELLULAR LOCATION: Isoform 3: Cytoplasm. Nucleus. INDUCTION: By mitogens and phorbol ester. DOMAIN: Contains two sets of 2 zinc-fingers, which are widely separated and recognize the same DNA sequence. There is a fifth zinc-finger in-between. SIMILARITY: Contains 5 C2H2-type zinc fingers. SEQUENCE CAUTION: Sequence=CAA35798.1; Type=Frameshift; Positions=Several; Sequence=CAH73909.1; Type=Erroneous gene model prediction; Sequence=CAH73982.1; Type=Erroneous gene model prediction; Sequence=CAI14768.1; Type=Erroneous gene model prediction; Sequence=CAI21070.1; Type=Erroneous gene model prediction;
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.
