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 CW domain is composed of four conserved cysteines and two tryptophan residues. The four cysteines could coordinate one zinc atom to form a new type of zinc finger. It is found exclusively in vertebrate, vertebrate-infected parasites and higher plants. The function of this zinc finger is not yet known but its taxonomic distribution and its association with a variety of domains involved in DNA binding, methylation, chromatin structure or ubiquitination suggest a putative role in epigenetic mechanisms and embryonic development [1].

The profile we developed covers the whole CW-type zinc finger.
