Genes affected
TERF1 (HGNC:11728): (telomeric repeat binding factor 1) This gene encodes a telomere specific protein which is a component of the telomere nucleoprotein complex. This protein is present at telomeres throughout the cell cycle and functions as an inhibitor of telomerase, acting in cis to limit the elongation of individual chromosome ends. The protein structure contains a C-terminal Myb motif, a dimerization domain near its N-terminus and an acidic N-terminus. Multiple transcripts of this gene are alternatively spliced products.
