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 LATERAL ORGAN BOUNDARIES (LOB) gene is expressed at the adaxial base of initiating lateral organs and encodes a plant-specific protein of unknown function. The N-terminal one half of the LOB protein contains a conserved approximately 100-amino acid domain (the LOB domain) that is present in 42 other Arabidopsis proteins and in proteins from a variety of other plant species. Genes encoding LOB domain (LBD) proteins are expressed in a variety of temporal- and tissue-specific patterns, suggesting that they may function in diverse processes [1].

The LOB domain contains conserved blocks of amino acids that identify the LBD gene family. In particular, a conserved C-x(2)-C-x(6)-C-x(3)-C motif, which is defining feature of the LOB domain, is present in all LBD proteins. It is possible that this motif forms a new zinc finger [1].

The profile we developed covers the entire LOB domain.
