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

Interleukin-7 (IL-7) [1] is a cytokine that serves as a growth factor for early lymphoid cells of both B- and T-cell lineages. Interleukin-9 (IL-9) [2] is a cytokine that supports IL-2 independent and IL-4 independent growth of helper T-cells.

Interleukin-7 and -9 seems to be evolutionary related [3]. As a signature pattern, we selected a conserved region located in the C-terminal section of the protein.
