Akuaporin 1
Akuaporin 1 adalah protein pada manusia yang dikodekan oleh gen AQP1.
AQP1 secara luas mengekspresikan saluran air yang fungsi fisiologisnya banyak dikarakteristikkan di dalam ginjal. Protein ini ditemukan pada membran plasma basolateral dan apikal tubulus proksimal, lengan menurun lengkung Henle, dan pada bagian menurun vasa rekta. Sebagai tambahan, protein ini juga ditemukan pada sel darah merah, endotelium vaskular, saluran pencernaan, kelenjar keringat, dan paru-paru.
Akuaporin ini tidak diregulasi oleh vasopresin (ADH).
Fungsi
suntingAkuaporin merupakan famili protein membran integral kecil terkait protein intrinsik mayor (MIP atau AQP0). Gen ini mengodekan akuaporin yang berfungsi sebagai protein saluran air molekuler. Protein ini merupakan homotetramer dengan 6 domain rentangan dwilapis dan situs N-glikosilasi. Fisik protein menyerupai protein saluran dan melimpah pada eritrosit dan tubulus ginjal. Gen yang mengodekan akuaporin ini menjadi kandidat mungkin untuk kelainan yang melibatkan ketidakseimbangan pada pergerakan cairan okular.[4]
