ID:CTF8_HUMAN DESCRIPTION: RecName: Full=Chromosome transmission fidelity protein 8 homolog; Short=hCTF8; FUNCTION: Chromosome cohesion factor involved in sister chromatid cohesion and fidelity of chromosome transmission. Component of one of the cell nuclear antigen loader complexes, CTF18-replication factor C (CTF18-RFC), which consists of CTF18, CTF8, DCC1, RFC2, RFC3, RFC4 and RFC5. The CTF18-RFC complex binds to single- stranded and primed DNAs and has weak ATPase activity that is stimulated the presence of primed DNA, replication protein A (RPA) and proliferating cell nuclear antigen (PCNA). The CTF18-RFC complex catalyzes the ATP-dependent loading of PCNA onto primed and gapped DNA. It also interacts with and stimulates POLH, which is suggestive of a protein network that coordinates DNA repair, recombination and chromosome cohesion reactions with replication fork progression. SUBUNIT: Component of the CTF18-RFC complex, which consists of CTF18, CTF8, DCC1, RFC2, RFC3, RFC4 and RFC5. The CTF18-RFC complex does not interact with the Rad9/Rad1/Hus1 complex. The CTF18-RFC complex interacts with POLH. CTF18/CTF8/DCC1 associate with PCNA. CTF8 exists as a dimer with DCC1. SUBCELLULAR LOCATION: Nucleus. Note=Associates with chromatin during S phase. TISSUE SPECIFICITY: Ubiquitously expressed, with abundant expression in kidney, skeletal muscle, testis, liver, ovary, and heart and moderate expression in prostate. Expression is significantly reduced in renal and prostate tumors. No differential expression in breast cancer cells, between lobular carcinoma and normal lobules. SIMILARITY: Belongs to the CTF8 family. CAUTION: mRNA expression studied by PubMed:12477976 does not differentiate between isoform 1 and isoform 2. SEQUENCE CAUTION: Sequence=AAQ08897.1; Type=Erroneous translation; Note=Wrong choice of CDS; Sequence=BAA91144.1; Type=Erroneous translation; Note=Wrong choice of CDS; Sequence=EAW83250.1; Type=Erroneous translation; Note=Wrong choice of CDS;
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.
