Day 69 has only 13 protein-coding genes (browser view), and the centromere of Chromosome 3. The genes include CGGBP1 (CGG triplet-repeat binding protein 1.) The gene for CGGBP1 encodes a protein that binds to DNA – as the name suggests, it binds to repeats of “CGG” in DNA, and turns on nearby genes. That makes it a transcription factor.
