Funkcija uredi
Protein kodiran ovim genom pripada potporodici fosfotransferaza. Ovaj kodirani enzim odgovoran je za treći i posljednji korak u stvaranju L-serina. Katalizira magnezij-ovisnu hidrolizu L-fosfoserina, a također je uključen u reakciju izmjene između L-serina i L-fosfoserina. Smatra se da je nedostatak ovog proteina povezan s Williamsovim sindromom.[7]
Klinički značaj uredi
Homozigotne ili složene heterozigotne mutacije u PSPH uzrokuju Neu-Laxov sindrom [9] i nedostatak fosfoserin-fosfataze.[10][11]
Modelni organizmi uredi
U proučavanju funkcije PSPH upotrebljeni su i modelni organizmi. Uvjetna linija nokaut-miševa zvana Psphtm1a(EUCOMM)Hmgu generirana je u Institutu Wellcome Trust Sanger.[12] Mužjaci i ženke podvrgnuti su standardiziranom fenotipskom pregledu[13] za određivanje delecijdkih učinaka.[14][15][16][17] Izvršeni su dodatni pregledi, kao što je dubinsko imunološko fenotipiziranje.[18]
