suggesting motif function could be determined. All predicted post-translational modification were confirmed to be conserved in the orthologous proteins. DEPDC1B evolution is predicted to follow the general species evolution. Paralogs DEPDC1B possesses two significant paralogs - DEPDC1A and DEPDC7 Multiple sequence alignment and phylogenetic analysis indicates DEPDC1A as the most recent paralog, diverging approximately 600 million years ago. DEPDC1A has been researched in several disease states. High expression of the protein in Multiple Myeloma (MM) malignant plasma cells is associated with patient fatality. The high expression has been confirmed using conditional lentiviral vector delivery “to inhibit growth of human melanoma cell lines (HMCLs), with a block in G2 phase of the cell cycle, p53 phosphorylation and stabilization, and p21Cip1 accumulation”9. In the same study it was concluded that DEPDC1A may contribute to the plasmablast features of MM cells, blocking differentiation. Study of DEPDC1A in bladder carcinogenesis revealed the gene as a possible antigen for the formation of bladder cancer cells. Using microarray and northern blotting confirmed the presence of unsubstantial amounts of the protein within the normal tissues, excluding the testis. Currently the gene is a potential target molecule for therapeutic treatment of bladder carcinogenesis. No data detailing significant function in DEPD7 has been published or recorded. References
