Human Gene GPS1 (ENST00000306823.10) from GENCODE V44
Description: Homo sapiens G protein pathway suppressor 1 (GPS1), transcript variant 2, mRNA. (from RefSeq NM_004127) RefSeq Summary (NM_004127): This gene is known to suppress G-protein and mitogen-activated signal transduction in mammalian cells. The encoded protein shares significant similarity with Arabidopsis FUS6, which is a regulator of light-mediated signal transduction in plant cells. [provided by RefSeq, Mar 2016]. Gencode Transcript: ENST00000306823.10 Gencode Gene: ENSG00000169727.14 Transcript (Including UTRs) Position: hg38 chr17:82,051,909-82,057,470 Size: 5,562 Total Exon Count: 13 Strand: + Coding Region Position: hg38 chr17:82,051,932-82,057,127 Size: 5,196 Coding Exon Count: 13
ID:CSN1_HUMAN DESCRIPTION: RecName: Full=COP9 signalosome complex subunit 1; Short=SGN1; Short=Signalosome subunit 1; AltName: Full=G protein pathway suppressor 1; Short=GPS-1; AltName: Full=JAB1-containing signalosome subunit 1; AltName: Full=Protein MFH; FUNCTION: Essential component of the COP9 signalosome complex (CSN), a complex involved in various cellular and developmental processes. The CSN complex is an essential regulator of the ubiquitin (Ubl) conjugation pathway by mediating the deneddylation of the cullin subunits of SCF-type E3 ligase complexes, leading to decrease the Ubl ligase activity of SCF-type complexes such as SCF, CSA or DDB2. The complex is also involved in phosphorylation of p53/TP53, c-jun/JUN, IkappaBalpha/NFKBIA, ITPK1 and IRF8/ICSBP, possibly via its association with CK2 and PKD kinases. CSN- dependent phosphorylation of TP53 and JUN promotes and protects degradation by the Ubl system, respectively. Suppresses G-protein- and mitogen-activated protein kinase-mediated signal transduction. SUBUNIT: Component of the CSN complex, composed of COPS1/GPS1, COPS2, COPS3, COPS4, COPS5, COP6, COPS7 (COPS7A or COPS7B) and COPS8. In the complex, it probably interacts directly with COPS2, COPS3, COPS4 and CSN5. Interacts directly with inositol kinase ITPK1. Interacts with CAPN8 (By similarity). SUBCELLULAR LOCATION: Cytoplasm. Nucleus. TISSUE SPECIFICITY: Widely expressed. DOMAIN: The PCI domain is necessary and sufficient for the interactions with other CSN subunits of the complex. Mediates the interaction with CAPN8 (By similarity). DOMAIN: The N-terminal part (1-216), which is not required for deneddylating activity and CSN complex formation, is nevertheless essential for other aspects of CSN complex function, such as repression of c-fos/FOS expression. PTM: Phosphorylated upon DNA damage, probably by ATM or ATR. SIMILARITY: Belongs to the CSN1 family. SIMILARITY: Contains 1 PCI domain. SEQUENCE CAUTION: Sequence=AAC50906.2; Type=Erroneous initiation;
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.
