Human Gene CLIC1 (uc011hbd.1) Description and Page Index
Description: Homo sapiens chloride intracellular channel 1 (CLIC1), mRNA. RefSeq Summary (NM_001288): Chloride channels are a diverse group of proteins that regulate fundamental cellular processes including stabilization of cell membrane potential, transepithelial transport, maintenance of intracellular pH, and regulation of cell volume. Chloride intracellular channel 1 is a member of the p64 family; the protein localizes principally to the cell nucleus and exhibits both nuclear and plasma membrane chloride ion channel activity.

Comments and Description Text from UniProtKB
ID:CLIC1_HUMAN DESCRIPTION: RecName: Full=Chloride intracellular channel protein 1; AltName: Full=Chloride channel ABP; AltName: Full=Nuclear chloride ion channel 27; Short=NCC27; AltName: Full=Regulatory nuclear chloride ion channel protein; Short=hRNCC; FUNCTION: Can insert into membranes and form chloride ion channels. Channel activity depends on the pH. Membrane insertion seems to be redox-regulated and may occur only under oxydizing conditions. Involved in regulation of the cell cycle. SUBUNIT: Monomer. Homodimer (in vitro). Interacts with TRAPPC2. Dimerization requires a conformation change that leads to the exposure of a large hydrophobic surface. In vivo, this may lead to membrane insertion. Interacts with AKAP9. SUBCELLULAR LOCATION: Nucleus. Nucleus membrane; Single-pass membrane protein (Probable). Cytoplasm. Cell membrane; Single-pass membrane protein (Probable). Note=Mostly in the nucleus including in the nuclear membrane. Small amount in the cytoplasm and the plasma membrane. Exists both as soluble cytoplasmic protein and as membrane protein with probably a single transmembrane domain. TISSUE SPECIFICITY: Expression is prominent in heart, placenta, liver, kidney and pancreas. DOMAIN: Members of this family may change from a globular, soluble state to a state where the N-terminal domain is inserted into the membrane and functions as chloride channel. A conformation change of the N-terminal domain is thought to expose hydrophobic surfaces that trigger membrane insertion. PTM: Hydrogen peroxide treatment causes a conformation change, leading to dimerization and formation of an intramolecular disulfide bond between Cys-24 and Cys-59. MISCELLANEOUS: The protein seems to have very low affinity for glutathione, even though glutathione binding was observed in protein crystals. SIMILARITY: Belongs to the chloride channel CLIC family. SIMILARITY: Contains 1 GST C-terminal domain. WEB RESOURCE: Name=Atlas of Genetics and Cytogenetics in Oncology and Haematology; URL="http://atlasgeneticsoncology.org/Genes/CLIC1ID50543ch6p21.html";

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.
ModBase Predicted Comparative 3D Structure on O00299
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.
