RCasp1 | mediates increased self-processing of pro-Casp6a into its active subunits | Homo sapiens |
Cloned (Comment) | Organism |
---|---|
the CASP6 gene generates an alternatively spliced transcript known as CASP6beta in addition to the CASP6alpha transcript that encodes pro-Casp6a. Individual expression of His-tagged pro-Casp6b and of catalytic mutant pro-Casp6aC163A in Escherichia coli strain BL21(DE3), Expression of pro-Casp6b from the pCep4beta construct in SK-N-SH cells | Homo sapiens |

additional information | alternatively spliced caspase-6B isoform inhibits the proteolytic self-activation of caspase-6A in vitro and in cells. But purified bacterially expressed recombinant pro-Casp6b does not possess catalytic activity and does not inhibit the active form of Casp6a | Homo sapiens |

General Information | Comment | Organism |
---|---|---|
additional information | the pro-Casp6b protein resulting from CASP6beta translation lacks part of the pro-domain and part of the large p20 subunit of pro-Casp6a | Homo sapiens |
physiological function | alternatively spliced caspase-6B isoform inhibits the activation of caspase-6A. Pro-Casp6b can negatively regulate pro-Casp6a activation in neurons and prevent Casp6a-mediated axonal degeneration. Pro-Casp6b inhibits RCasp1-mediated processing of Pro-Casp6a in vitro | Homo sapiens |
