Zusammenfassung: | A MORT1 gene initially cloned from HeLa cells and identified as a member of the receptor mediated apoptotic pathway, is expressed in the human neuronal cell line, NTERA2. Isolation of the MORT1 from this cell line revealed a transcript isoform that differed from the known MORT1 sequence by a deletion of 21 base pairs (bp 172-192 of the coding sequence). Cloning of MORT1 from adult human brain revealed two isoforms, one similarly deleted for bp 172-192, the other with a basepair substitution, A for G at position 173. Assessment of MORT1 function in a yeast two hybrid system indicates that the deleted and intact forms of MORT1 differ in their capacity to interact with other members of the apoptotic pathway. |
