Cloning, sequence and expression of two distinct human interleukin-1 complementary DNAs
Two distinct but distantly related complementary DNAs encoding proteins sharing human interleukin-1 (IL-1) activity (termed IL-lα and IL-1β), were isolated from a macrophage cDNA library. The primary translation products of the genes are 271 and 269 amino acids long, although expression in Escherich...

Zusammenfassung: | Two distinct but distantly related complementary DNAs encoding proteins sharing human interleukin-1 (IL-1) activity (termed IL-lα and IL-1β), were isolated from a macrophage cDNA library. The primary translation products of the genes are 271 and 269 amino acids long, although expression in
Escherichia coli
of the carboxy-terminal 159 and 153 amino acids produces IL-1 biological activity. |
