Abstract

The signal transduction network controlling protein degradation in the striated body-wall muscle of C. elegans has been shown to be composed of stimulatory signaling from the FGF receptor and inhibitory signaling from the IGF receptor engaged in cross talk at the level of the Raf-MEK-MAPK cascade. Calcium/calmodulin-dependent protein kinase II (CaMKII) is an additional, pro-degradation input into the network at the level of Raf. Splice forms of CaMKII may play a role in effective CaMKII signaling. The IGFR/FGFR/CaMKII network regulates protein degradation via autophagy. Degradation caused by increase of the pro-degradation signal from CaMKII can be suppressed by increase of opposing IGFR signaling, and degradation caused by decrease in the IGFR signal can be suppressed by decreased CaMKII signaling. This implies that regulation of protein degradation is based on integration of multiple signals by Raf and not on absolute amounts of individual signals.
