Mitotic cell division is the most fundamental task of all living cells. Cells have intricate and
tightly regulated machinery to ensure that mitosis occurs with appropriate frequency and high …

Myosin VI is a molecular motor involved in intracellular vesicle and organelle transport. To
carry out its cellular functions myosin VI moves toward the pointed end of actin, backward in …

Intracellular transport is typically bidirectional, consisting of a series of back and forth
movements. Kinesin-1 and cytoplasmic dynein require each other for bidirectional transport of …

The kinesin motor typically binds to cargo through its light chains. In this issue Glater et al. (p.
545 ) demonstrate a new type of linkage through the adapter protein, milton, and the …

The antitumor activity of the sesquiterpene lactone parthenolide, an active ingredient of
medicinal plants, is believed to be due to the inhibition of DNA binding of transcription factors NF-…

Kinesin-1 is a molecular motor protein that transports cargo along microtubules. Inside cells,
the vast majority of kinesin-1 is regulated to conserve ATP and to ensure its proper …

President Bush is correct to focus on the problems posed by failed and failing states. The
NSS also represents a new direction for this administration, which had not previously …

Miro is a highly conserved calcium‐binding GTPase at the regulatory nexus of mitochondrial
transport and autophagy. Here we present crystal structures comprising the tandem EF …

Tamm–Horsfall protein (THP), also known as uromodulin, is a kidney-specific protein
produced by cells of the thick ascending limb of the loop of Henle. Although predominantly …
