interleukin-1 converting enzymemedical dictionary

<biochemistry> Cytoplasmic cysteine protease that is uniquely responsible for cleaving proIL-1_ (31 or 33 kD) into mature IL-1_ (17.5 kD), the active cytokine is then released by a nonstandard mechanism (there is no signal sequence and it does not pass through the Golgi).

The enzyme seems to be composed of two nonidentical subunits derived from a single proenzyme. The ICE gene has some homology with the ced 9 gene of C. Elegans, the product of which is involved in mediating cell death by apoptosis.
