Genetic robustness and functional evolution of gene duplicates.

abstract：:Members of the HMG-I(Y) family of mammalian nonhistone proteins are of importance because they have been demonstrated to bind specifically to the minor groove of A.T-rich sequences both in vitro and in vivo and to function as gene transcriptional regulatory proteins in vivo. Here we report the cloning, sequencing, cha...
