SLURP1
Lučeni Ly-6/uPAR-srodni protein 1 je protein koji je kod ljudi kodiran genom SLURP1.[5][6][7] Ima protivupalno djelovanje, kao supresor tumora i antagonizira nikotinske receptore.[8]
Aminokiselinska sekvenca uredi
Dužina polipeptidnog lanca je 103 aminokiseline, а molekulska težina 11.186 Da.[9]

Funkcija uredi
Protein kodiran ovim genom član je porodice Ly6/uPAR, ali mu nedostaje signalna sekvenca za sidrenje GPI. Izlučuje se u krv[6], a ponekad se nalazi i u spermi, kada se ekstrahira u zigot koji se veže za receptor α7-acetilholina.[8] Prikazano je da djeluje kao endogeni supresor tumora smanjujući migraciju i invaziju stanica posredujući svoj vlastiti antitumorski učinak i antagonizirajući pro-maligne učinke nikotina.[8]
Mutacije u ovom genu povezane su s mljetskom bolešči (Mal de Meleda), rijetkim autosomno recesivnim kožnim poremećajem kojeg karakterizira upalna dlanskotabanska hiperkeratoza. To je posljedica gubitka SLURP1, što dovodi do disfunkcionalne epitelne diferencijacije.[10] and an increased secretion of the inflammatory cytokines TNFα, IL1, IL-6, and IL-8.[11][12]
Ovaj gen nalazi se u istoj hromosomskoj regiji kao i nekoliko članova porodice glikoproteinskih receptora Ly6/uPAR.[7]
