ASDB: database of alternatively spliced genes

A database of alternatively spliced genes (ASDB) has been constructed based on (i) the results of the analysis of Swiss-Prot entries containing produc ts of these genes and (ii) clustering procedure joining proteins that could arise by alternative splicing of the same gene. ASDB incorporates informat ion about alternatively spliced genes, their products and expression patter ns. It can be searched in order to find all products of alternative splicin g produced in a particular tissue or a given organism, or all variants gene rated by a particular transcript. ASDB currently contains about 1700 protei n sequences and can be accessed via the Internet at URL http://cbcg.nersc.g ov/asdb.
