Regulacijski protein povratne sprege GTP ciklohidrolaze 1 je enzim koji je kod ljudi kodiran genom GCHFR.

Regulatorni povratni signalni protein za GTP ciklohidrolaze I veže se i posreduje inhibiciju tetrahidrobiopterin-GTP ciklohidrolaze I. Regulatorni protein, GCHFR, sastoji se od homodimera. Pretpostavlja se da GCHFR može imati ulogu u regulaciji metabolizma fenilalanina u jetri i u proizvodnji biogenih aminskih neurotransmitera i dušik-oksida.

Aminokiselinska sekvenca

Dužina polipeptidnog lanca je 84 aminokiseline, a molekulska težina 9.698 Da..
