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

Data class Domain;
Predictors PROSITE; PS51506; CBL_PTB
Name Cbl-type phosphotyrosine-binding (Cbl-PTB) domain
Function Cbl-PTB is composed of three interacting domains: a four-helix bundle (4H), an EF-hand calcium-binding domain, and a divergent SH2 domain. The calcium-bound EF-hand wedges between the 4H and SH2 domains, and roughly determines their relative orientation. The three domains together form an integrated phosphoprotein-recognition module.
Scope(s) Eukaryota
Viruses

Comments [?]

DOMAINThe N-terminus is composed of the phosphotyrosine binding (PTB) domain, a short linker region and the RING-type zinc finger. The PTB domain, which is also called TKB (tyrosine kinase binding) domain, is composed of three different subdomains: a four-helix bundle (4H), a calcium-binding EF hand and a divergent SH2 domain.
