Plekstrinski homologni domen (PH domen) je proteinski domen sa aproksimativno 120 aminokiselina. On se javlja u širokom opsegu proteina koji učestvuju u intraćelijskoj signalizaciji ili su konstituenti citoskeletona.[1][2][3][4][5][6][7]
Ovaj domen je prisutan u fosfatidilinozitolnim lipidima unutar bioloških membrana (kao što je fosfatidilinozitol (3,4,5)-trisfosfat i fosfatidilinozitol (4,5)-bisfosfat),[8] i proteinima poput βγ-podjedinica heterotrimernih G proteina,[9] i proteinske kinaze C.[10] Putem tih interakcija, PH domeni učestvuju u regruitovanju proteina u različite membrane, te ih sortiraju u odgovarajuće ćelijske kompartmane ili im omogućavaju da formiraju interakcije sa drugim komponentama puteva prenosa signala.
