Su(var)3-7 | Suppressor of variegation 3-7 (Su(var)3-7) encodes a protein associated with heterochromatin. Increasing the amount of the product of Su(var)3-7 triggers heterochromatin expansion and epigenetic gene silencing. (1250 aa) | ||||
cuff | Cutoff (cuff) encodes a protein that interacts with the products of rhi and del in a germline complex that allows noncanonical transcription of dual-strand piRNA clusters. The product of cuff is therefore an integral part of the piRNA response to transposon activity in the germline. In its absence, a DNA damage checkpoint is activated leading to ventralization of the egg and embryo. (384 aa) |
