Glutamine And Serine Rich Protein 1 (QSER1)

QSER1 protein contains two high conserved domains found not only in QSER1 but also in other protein products. This property was conserved from the human QSER1 to the Coelacanth QSER1. Multiple conserved nuclear localization signals were also predicted within the QSER1 protein by pSORT. Predictions of the QSER1 protein structure indicate that the protein contains many alpha helices. NCBI cBLAST predicted structural similarity between the QSER1 protein and the Schizosaccharomyces pombe (fission yeast) RNA Polymerase II A chain. The two regions of similarity occur between amino acids 56-194 and 322-546. This first region (56-194) is a regulatory region in both the human and yeast RNA Polymerase II containing multiple repeats of the sequence YSPTSPSYS.
