Novel nucleolar GTPases and method for controlling proliferation of cells

摘要

There is provided an isolated polypeptide comprising an amino acid sequence at least 85% homologous to SEQ ID NO: 2 or SEQ ID N: 4, or a conservative variant thereof, wherein the polypeptide regulates proliferation of a cell. There is also provided an isolated polynucleotide encoding the polypeptide of the invention. There is also provided a method for inhibiting the proliferation of a cell, comprising altering the level of a polypeptide comprising an amino acid sequence at least 85% homologous to SEQ ID NO: 2 or SEQ ID NO: 4 in the cell, thereby inhibiting proliferation of the cell.
