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.

Description

The Nir/rdgB (N-terminal domain-interacting receptor/Drosophila retinal degeneration B proteins) family has been identified in a variety of eukaryotic organisms, ranging from worms to mammals. Members of this family are implicated in regulation of lipid trafficking, metabolism, and signaling. The Nir/rdgB proteins contain a 180 amino-acids-long conserved region in the central part of the protein. This domain contains four conserved residues, DDHD, which may form a metal-binding site. This domain is named DDHD after these four residues. This pattern of conservation of metal-binding residues is often seen in phosphoesterase domains [1].

The DDHD domain is found in the central part of Nir/rdgB proteins, as well as the C-terminal part of the phosphatidic acid-preferring phospholipase A1. The DDHD domain function is not currently known but it may be implicated in phospholipid metabolism, membrane turnover, or intracellular trafficking [1].

The profile we developed covers the entire DDHD domain.
