We are deeply saddened by the passing of Amos Bairoch (1957–2025), the creator of PROSITE. We wish to dedicate our latest paper, published shortly before his death, to him. He will always be a source of inspiration to us.
Our deepest condolences go out to his family and friends, and to all those who had the privilege of working with him. Rest in peace, Amos. Your work will live on long after you are gone.
Amos Bairoch

Description

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.
