What is the official name of the UVSSA gene?The official name of this gene is “UV-stimulated scaffold protein A.” UVSSA is the gene's official symbol. The UVSSA gene is also known by other names, listed below. Read more about gene names and symbols on the About page. What is the normal function of the UVSSA gene?The UVSSA gene provides instructions for making a protein that is involved in repairing DNA damaged by ultraviolet (UV) rays from the sun. The damage can block vital cell activities such as gene transcription, which is the first step in protein production. If left uncorrected, DNA damage accumulates, which causes cells to malfunction and can lead to cell death. Cells have several mechanisms to correct DNA damage. The UVSSA protein is involved in one mechanism that repairs damaged DNA within active genes (those genes undergoing gene transcription). When DNA in active genes is damaged, the enzyme that carries out gene transcription (RNA polymerase) gets stuck, and the process stalls. Researchers think that the UVSSA protein helps remove RNA polymerase from the damaged site, so the DNA can be repaired. Part of the UVSSA protein's role in this process is to ensure that another important protein called CSB is not broken down by exposure to UV rays. How are changes in the UVSSA gene related to health conditions?
Where is the UVSSA gene located?Cytogenetic Location: 4p16.3 Molecular Location on chromosome 4: base pairs 1,341,103 to 1,381,836 The UVSSA gene is located on the short (p) arm of chromosome 4 at position 16.3. More precisely, the UVSSA gene is located from base pair 1,341,103 to base pair 1,381,836 on chromosome 4. See How do geneticists indicate the location of a gene? in the Handbook.
