| Type: | Family | Name: | Cryptochrome, DASH |
| Description: | Photolyases and cryptochromes are related flavoproteins. Photolyases harness the energy of blue light to repair DNA damage by removing pyrimidine dimers. Cryptochromes do not repair DNA and are presumed to act instead in some other (possibly unknown) process such as entraining circadian rhythms. This entry describes the cryptochrome DASH subfamily, one of at least five major subfamilies, which is found in plants, animals, marine bacteria, etc. Members of this family bind both folate and FAD. They may show weak photolyase activity in vitro but have not been shown to affect DNA repair in vivo. Rather, DASH family cryptochromes have been shown to bind RNA (Vibrio choleraeVC_1814), or DNA, and seem likely to act in light-responsive regulatory processes. | Short Name: | Cryptochrome_DASH |
