Elk-1 interacts with dynein upon serum stimulation but independent of serine 383 phosphorylation

Cell Mol Neurobiol. 2012 Mar;32(2):185-9. doi: 10.1007/s10571-011-9750-x. Epub 2011 Sep 21.

Abstract

Elk-1 belongs to the Ternary Complex Factor (TCF) subfamily of the ETS (from E26 viral oncogene) domain superfamily of transcription factors, and has been known as a regulator of mitogen-induced immediate early gene transcription upon Mitogen Activated Protein Kinase (MAPK) activation. Elk-1 has been previously shown to interact with neuronal microtubules, and here we show that P-S383-Elk-1, in addition to co-localizing with motor proteins kinesin, Eg5 and Mitotik Kinesin-Like Protein (MKLP) at the mitotic spindles, it physically interacts with dynein in a serum induction-dependent but Ser383 phosphorylation-independent manner.
