The expression of the human Ki‐67 protein is strictly associated with cell proliferation.
During interphase, the antigen can be exclusively detected within the nucleus, whereas in …

This article reviews findings up to the end of 1997 about the inducible transcription factors
(ITFs) c-Jun, JunB, JunD, c-Fos, FosB, Fra-1, Fra-2, Krox-20 (Egr-2) and Krox-24 (NGFI-A …

The antigen defined by mAb Ki-67 is a human nuclear protein the expression of which is
strictly associated with cell proliferation and which is widely used in routine pathology as a" …

Symbiotic nitrogen-fixing root nodules on legumes are founded by root cortical cells that de-
differentiate and restart cell division to establish nodule primordia. Bacterial microsymbionts …

Nuclear targeting sequences are essential for the transport of proteins into the nucleus. The
seven-amino-acid nuclear targeting sequence of the SV40 large T antigen has been …

Active nuclear import of protein is controlled by nuclear localization signals (NLSs), but
nuclear export is not understood well. Nuclear trafficking of the catalytic (C) subunit of cAMP …

To automate examination of massive amounts of sequence data for biological function, it is
important to computerize interpretation based on empirical knowledge of sequence-function …

Because influenza virus replicates in the nucleus and buds from the plasma membrane, its
ribonucleoproteins (RNPs) must undergo bidirectional transport across the nuclear …

The DNA binding activity of Fos and Jun is regulated in vitro by a post‐translational
mechanism involving reduction‐oxidation. Redox regulation occurs through a conserved …

NF-kappa B is an inducible transcription factor comprised of a 50-kD (p50) and a 65-kD
(p65) subunit. Induction of NF-kappa B activity, which is a critical event in many signal …
