Identification of five new genes, closely related to the interleukin-1beta converting enzyme gene, that do not encode functional proteases.

Interleukin-1beta converting enzyme (ICE) was the first identified member of a growing family of cysteine proteases that now includes ten mammalian homologs. Within this large family, two functional proteins, denoted TX and TY share 60% amino-acid identity with ICE in the mature protein and, together with ICE, constitute the ICE subfamily. The present study describes the identification of five new gene sequences, denoted S1-S5, closely related to ICE and TX and belonging to this subfamily. Sequences were identified using genomic Southern-blot analysis of human DNA with probes corresponding to ICE and TX exon 6. Using PCR amplification and cloning, the complete exon-6 sequence of these new genes was identified; three exhibit around 90% identity with Ice within exon 6, whereas the two others share about 70% identity with Ice. Examination of open reading frames and of amino acids essential for ICE activity indicate that none of these genes encodes for a functional protease. In conclusion, extensive analysis of the genes closely related to Ice shows that the Ice subfamily is constituted of eight members. Three of them encode for functional proteases (ICE, TX and TY) whereas the remaining members probably correspond to pseudogenes.[1]
