Background: IL-18 BPa

Interleukin 18 binding proteins are secreted glycoproteins which antagonize IL-18 activity by binding IL-18 and blocking its biological activity. Alternative splicing of the IL-18 BP gene produces at least four isoforms that differ in affinity for IL-18. The IL-18 BP isoforms a and c each contain one immunoglobulin (Ig)-like C2-type domain while isoforms b and d lack a complete Ig-like domain.

Long Name

Interleukin 18 Binding Protein Isoform a

Alternate Names

IL18 BPa, IL18BP

Entrez Gene IDs

10068 (Human); 84388 (Rat); 107126419 (Cynomolgus Monkey)
