Phosphorylation of heterogeneous nuclear ribonucleoprotein K at an extracellular signal-regulated kinase phosphorylation site promotes neurofilament-medium protein expression and axon outgrowth in Xenopus.

Abstract excerpt

Post-transcriptional control of cytoskeletal genes fine-tunes the supply of structural materials to growing axons in response to extracellular cues. In Xenopus, heterogeneous nuclear ribonucleoprotein K (hnRNPK) plays a crucial role in the nuclear export and translation of multiple cytoskeletal-related mRNAs required for axon outgrowth, and as a substrate of multiple kinases, is thus a likely molecular target of...
