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 P0 protein is a major structural glycoprotein of the peripheral nervous system (PNS) myelin which probably plays an important role for the formation and the maintenance of myelin structure [1,2,3].

P0 is a protein of about 28 Kd that consists of three domains: a N-terminal extracellular domain of about 125 residues which seems to form a V-type immunoglobulin domain; a transmembrane region, and a cytoplasmic C-terminal domain of about 70 residues which contains many positively charged residues and which is a substrate of some serine protein kinases.

P0 is well conserved across species. As a signature pattern we selected a region located in the C-terminal part of the cytoplasmic domain that contains many positive charges and serine residues that could be phosphorylated.

November 1997 / Pattern and text revised.
