<p>This subsection of the <a href="http://www.uniprot.org/help/names_and_taxonomy_section">Names and taxonomy</a> section provides an exhaustive list of all names of the protein, from commonly used to obsolete, to allow unambiguous identification of a protein.<p><a href='/help/protein_names' target='_top'>More...</a></p>Protein namesi

  • Recommended name:
    Proactivator polypeptide-like 1
  • Recommended name:
    Prosaposin

<p>This subsection of the <a href="http://www.uniprot.org/help/function_section">Function</a> describes the function(s) of a protein.<p><a href='/help/function' target='_top'>More...</a></p>Functioni

  • May activate the lysosomal degradation of sphingolipids.
  • Prosaposin: Behaves as a myelinotrophic and neurotrophic factor, these effects are mediated by its G-protein-coupled receptors, GPR37 and GPR37L1, undergoing ligand-mediated internalization followed by ERK phosphorylation signaling.
  • Saposins are specific low-molecular mass non-enzymic proteins, they participate in the lysosomal degradation of sphingolipids, which takes place by the sequential action of specific hydrolases.
