We report here on the identification of a 17 kDa variant of the 14 kDa Id-3 protein termed Id-3L (long version) which possesses a unique 60 amino acid carboxy-terminus generated by read through of a ' coding intron ' and alternative splicing .
 ( protein: 60 amino acid carboxy-terminus, None) , ( protein: Id-3, None) , ( protein: Id-3L, None) , ( DNA: coding intron, None) , ( protein: 14 kDa Id-3, None) , ( protein: 17 kDa variant, None)
