Gene: [10q25/CASP7] caspase 7, apoptosis-related cysteine protease; craniofacial dysostosis 1? (Crouzon syndrome; MIM:123500);

COM

Using radiation hybrids the CASP7 gene has been mapped to chromosome 10q25.1-q25.2 (Tiso-1996). Tiso et al. also suggested Crouzon craniofacial dysostosis as a candidate genetic disease at the 10q25-q26 locus (see also GEM:10q2/FGFR2)."

GEN

One cDNA type, MCH3-alpha, encodes a 303-amino acid polypeptide with a predicted molecular mass of approximately 34 kD. The second, presumably alternatively spliced, cDNA type, named MCH3-beta, which contains a deletion and insertion within the sequence and a much longer 5-prime untranslated region; the insertion in the MCH3-beta sequence produces a frame shift which results in a shorter, 253-amino acid, approximately 28-kD polypeptide lacking the QACRG pentapeptide, believed to be the cysteine protease active site of all members of the ICE/CED-3 family. Active MCH3-alpha protein is made by the cleavage of proMCH3-alpha into 2 subunits, p20 and p12 (Fernandes-Alnemri-1995)."

FUN

Casp-7-beta (MCH3-beta) has been proposed to act as a negative regulator of apoptosis by acting as a dominant inhibitor of the activity of CASP-7- alpha (MCH3-alpha) (Fernandes-Alnemri-1995)."

MOP

Fernandes-Alnemri et al. (Fernandes-Alnemri-1995) found that active MCH3-alpha protein is made by the cleavage of proMCH3-alpha into 2 subunits, p20 and p12."
