Fernandes-Alnemri et al. (1995) isolated MCH2, a member of the ced-3 subfamily of apoptotic proteases, by performing PCR on human Jurkat T lymphocytes using degenerate oligonucleotides corresponding to conserved peptides in known apoptotic cysteine proteases. The gene, also symbolized CASP6, encodes a 34-kD protein that is highly homologous to human CPP32 (600636), C. elegans ced-3, mammalian Ich1/Nedd2 (600639), and mammalian interleukin-1-beta converting enzyme (147678). Fernandes-Alnemri et al. (1995) observed 1.7-kb (alpha) and 1.4-kb (beta) transcripts expressed in Jurkat lymphocytes and other cell lines. The authors suggested that these transcripts are alternate splicing variants and found that the alpha, but not the beta, MCH2 protein has protease activity. They also found that MCH2-alpha protein can cleave poly(ADP-ribose) polymerase (173870) in vitro and that its overexpression induces apoptosis in insect Sf9 cells, suggesting that MCH2 is a mediator of apoptosis in mammalian cells
