Subunit hemoglobin alfa^[4] ialah sebuah protein hemoglobin yang dikodkan oleh gen HBA1 dalam manusia.^[5]

Gen

Kelompok gen globin alfa manusia yang terletak pada kromosom 16 menjangkau kira-kira 30 kb dan merangkumi tujuh lokus: 5'- zeta - pseudozeta - mu - pseudoalfa-1 - alfa-2 - alfa-1 - teta - 3'. Urutan pengekodan alpha-2 (HBA2) dan alpha-1 (HBA1; gen ini) adalah sama. Gen ini berbeza sedikit di wilayah 5' tidak ditranslasikan dan intron, tetapi ia berbeza ketara di wilayah 3' tidak ditranslasikan.^[5]

Protein

Dua rantai alfa dengan dua rantai beta membentuk HbA yang merangkumi kira-kira 97% jumlah hemoglobin dalam kehidupan dewasa normal; rantai alfa bergabung dengan rantai delta untuk membentuk HbA-2 yang membentuk baki 3% hemoglobin dewasa bersama dengan hemoglobin janin (HbF).

Kepentingan klinikal

Talasemia alfa terhasil daripada pemadaman setiap gen alfa serta pemadaman kedua-dua HBA2 dan HBA1; beberapa talasemia alfa bukan pemadaman juga telah dilaporkan.^[5]

Interaktsi

Subunit hemoglobin alfa telah diperhatikan berinteraksi dengan subunit hemoglobin beta (HBB).^[6]^[7]
