PROSITE documentation PDOC51271
WAPL domain profile


The WINGS APART-LIKE (WAPL) protein of Drosophila melanogaster regulates heterochromatin structure. It is required to hold sister chromatids of meiotic heterochromatin together and is implicated in both heterochromatin pairing during female meiosis and the modulation of position-effect variegation (PEV). Although the high-sequence conservation is limited to a third of the protein sequence, a WAPL homologue has been identified in mammals. Mammalian WAPL may play a significant role in meiosis as does the Drosophila one. Human WAPL is overexpressed in invasive human cervical cancers and is often associated with cervical carcinogenesis [1,2].

The profile we developed covers the entire WAPL domain.
