N-HH movement between cells is facilitated by the glypicans aka heparan sulphate proteoglycan proteins (HSPGs), Dally (DALLY) and Dally-like protein (DLP) which require heparan sulphate modification by the Exostosin (EXT) family proteins tout-velu (TTV), brother of tout-velu (BOTV) and sister of tout-velu (EXT2) for this purpose. N-HH can form multimers, associated with enhanced movement of vertebrate Sonic Hedgehog, and can associate with lipophorin-containing lipophorin particles which appear to enhance N-HH movement. The protein Shifted (SHF) also facilitates HH movement.
