Funkcija
urediSmatra se da ovaj gen igra važnu ulogu u homeostazi kalcija. Alternativna prerada ovog gena rezultira u pet varijanti transkripta koje se razlikuju u translaciji proteina, kodiranju katalitskih domena i tkivnoj ekspresiji. Varijacije među ovim transkriptima utiču na njihove funkcije, koje uključuju uloge u procesu skladištenja i oslobađanja kalcija u endoplazmatskom i sarkoplazmatskom retikulumu, kao i hidroksilaciji asparaginske kiseline i asparagina u domenama različitih proteina sličnih epidermnim faktorima rasta.[7]
Klinički značaj
urediJoš 1996. prekomjerna ekspresija HAAH prepoznata je kao pokazatelj karcinoma kod ljudi. Dalja istraživanja su povezala povišene nivoe HAAH (različito u zahvaćenom tkivu ili serumu) sa hepatoćelijskim (jetrenim) karcinomom[9][10] adenokarcinomom (rak gušterače),[11] kolorektumskim kancerom,[12] rakom prostate.[10] i kancerom pluća.[13] Studija gušterače [11] pokazala je povišeni HAAH samo u oboljelom tkivu, ali ne i u susjednom normalnom i upaljenom tkivu.
Mutacije u ASPH-u uzrokuju Traboulsijev sindrom.[14]
