Inhibits neurite branching, arbor length and neurite complexity (By similarity). Inhibits EGF-mediated p42/44 ERK signaling (By similarity). Negatively regulates the MAPK cascade, resulting in a reduction of extracellular matrix protein accumulation . May function as an antagonist of fibroblast growth factor (FGF) pathways and may negatively modulate respiratory organogenesis .
Subcellular locations: Cytoplasm
Widely expressed; particularly in the fetal tissues. Expressed in the brain with expression the highest in Purkinje cells in the cerebellum (at protein level) . Expressed in the myocardium of the heart .
