CCDC186 is a protein that in humans is encoded by the CCDC186 gene [5] The CCDC186 gene is also known as the CTCL-tumor associated antigen with accession number NM_018017. [6]
CCDC186 has the chromosome location of 10q25.3 and is 53,750 bases in size oriented on the minus strand. PSORTII Protein k-NN Prediction indicated that C10orf118 is 65.2% of the time nuclear, 17.4% cytosolic, 8.7% mitochondrial, 4.3% vesicles of secretory system, and 4.3% endoplasmic reticulum. [7]
Analysis of gene expression in humans and other species indicates C10orf118 is ubiquitously expressed in all tissue types at varying developmental stages. An EST profile from NCBI displayed the greatest expression in bone marrow, kidneys, and the prostate cell lines. Breakdown by health state indicates high expression of C10orf118 in bladder carcinoma and prostate cancer. [8]
The protein of CCDC186 (NP_060487) is 898 amino acids in length. The predicted molecular weight is 103.7kdal and the isoelectric point is predicted to be 5.92. [9]
A serine rich region is observed in amino acids 710-747. A compositional analysis revealed that C10orf118 is Proline (1.1%) poor and Glutamic acid (14.1%) and Lysine (12.0%) rich. [9]
CCDC186 protein was found to interact with proteins PLEKAH5, Ezra, GAMMAHV.ORF23, and SMAD3. [10] [11]
Orthologous sequences of CCDC186 were not found to be in bacteria, archea, protist, or plants. CCDC186 has no human paralogs. The date of divergence for the orthologous sequences highly correlates with the sequences similarity in that the percent identity decreases as you go back in time. Closely related orthologs include mammals and birds and moderately related orthologs include other vertebrates such as fish, reptiles, and amphibians. Distantly related orthologous sequences are primarily observed in invertebrates. [9] [12]
