Distrobrevin alfa je protein koji je kod ljudi kodiran genom DTNA.^[5]^[6]^[7]

Funkcija[uredi | uredi izvor]

Protein kojeg kodira ovaj gen pripada potporodicama distrobrevina i distrofina. Komponenta je proteinskog kompleksa povezanog sa distrofinom (DPC). DPC sastoji se od distrofina i nekoliko integralnih i perifernih membranskih proteina, uključujući distroglikan, sarkoglikani, sintrofin i alfa– i beta-distrobrevin. DPC se lokalizira na sarkolemi, a njegov poremećaj povezan je s različitim oblicima mišićne distrofije. Ovaj protein može biti uključen u stvaranje i stabilnost sinapsi, kao i u grupiranje nikotinskog receptora acetilholina. Identificirano je više alternativno spojenih varijanti transkripata koji kodiraju različite izoforme.^[7]

Klinički značaj[uredi | uredi izvor]

Mutacije u DTNA povezane su s Meniereovom bolešću.^[8]^[9]

Interakcije[uredi | uredi izvor]

Pokazano je da je DTNA u interakcijama sa distrofinom.^[10]
