- Abstract
Survivin gene and its two alternatively spliced variants, survivin-2 B and survivin- Delta Ex3 gene were cloned from human breast cancer cell lines B-cap37 firstly. A new gene designated as survivin-image (SI) was cloned from above cell lines, which has not been reported yet to clone from any cell lines. It was found that the novel gene 507 bp comprises partial survivin gene (345 bp), partial image gene (155 bp) of eye cancer and other insertion of 7 bp by analyzing with a series of recent bioinformatics software at the level of nucleotide and protein deduced. Predicted 3-D structures of the new molecule showed greatly similar to that of survivin in N-terminal containing BIR by homology modeling. These results suggested SI gene (GenBank accession No.AY830084) might be a novel alternatively spliced isoforms of the survivin gene involved in other functional significances related to tumorigenesis.
