Sequence 2 had the protein, presenilin-2-like, Equus przewalskii . The protein is also known as PSEN2 gene. This gene helps process proteins that transmit chemical signals from the cell membrane to the nucleus. When the chemical signals fire to the nucleus, they turn on genes that make for the cell to grow and mature. The specific role, presenilin is known for, is processing the amyloid precursor protein. The amyloid precursor protein is found in the brain and some tissues. Presenilin gets with enzymes to cut amyloid precursor into segments. Segments that are created throughout the process are known as soluble amyloid precursor protein (SAPP) and amyloid beta peptide. The segment, SAPP is the protein that relates to growth and deals with
