CC   -!- FUNCTION: Stimulates the proliferation of neural cells.
CC       {ECO:0000250|UniProtKB:P69208}.
CC   -!- SUBUNIT: May interact with SORL1 (via N-terminal ectodomain); this
CC       interaction is impaired in the presence of SORL1 propeptide.
CC       {ECO:0000250|UniProtKB:P69208}.
CC   -!- CAUTION: This peptide was first isolated from nerve cells of hydra and
CC       was called head activator by the authors, because it induced head-
CC       specific growth and differentiation in this animal. It has been found
CC       in mammalian intestine and hypothalamus. {ECO:0000305}.
