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 myosin superfamily consists of at least 15 distinct classes of presumed actin-based molecular motors. All members of the superfamily share a similar motor domain and a tail portion which is diagnostic of the class [1].

Class V myosins are actin-based molecular motors that function in relatively long-range movements of many intracellular cargoes including organelles, membrane vesicles, and mRNA [2]. These motors are ubiquitously found in all eukaryotes. Class V myosins are characterised by the presence of a conserved globular domain at the C-terminus of the tail portion: the dilute domain [3]. Myosin V moves via attachment of its amino terminal head (motor) domain to actin cables; its carboxyl terminal dilute domain anchors it to cargoes via attachments to organelle-specific receptors [2,4].

The dilute domain is also found in the afadin family. Afadins are nectin and actin filament-binding proteins that connect nectin to the actin cytoskeleton [5].

The profile we developed covers the whole dilute domain.
