shc-1

Gene
shc-1
Protein
SHC-transforming protein homolog 1
Organism
Caenorhabditis elegans
Length
316 amino acids
Function
Scaffold protein which plays an important role in the activation of the JNK pathway composed of mlk-1, mek-1 and kgb-1; by bringing together mek-1 and mlk-1, promotes mlk-1-mediated phosphorylation and activation of mek-1 which in turn phosphorylates kgb-1 (PubMed:18832074, PubMed:18809575). In addition, negatively modulates the activation of the insulin/IGF-1-like signaling (IIS) probably by inhibiting the insulin receptor daf-2. Positively regulates the activity of the transcription factor daf-16/FOXO by both inhibiting IIS and activating the JNK pathway (PubMed:18832074). Involved in the response to several environmental stresses including heavy metal ions (Cu(2+) and Cd(2+)), heat, oxidative and protein misfolding (ER) stresses (PubMed:18832074, PubMed:18809575). Plays a role in life span and egg laying (PubMed:18832074, PubMed:23072806). Plays a role in axon regeneration after injury (PubMed:23072806, PubMed:27984580).
