GeneID: 36



Names

Common Name: AHSP Type: Gene
Chromosome: 16 (NC_000016.10) Locus: NT_010393.16 (AHSP)
HUGO Symbol: AHSP Full Name: alpha hemoglobin stabilizing protein
Exons: 3 Introns: 2

Description:
AHSP is an abundant erythroid-specific protein that forms a stable complex with free alpha-globin but not beta-globin or the heterotetrameric haemoglobin A (α2β2). Moreover, AHSP specifically protects free alpha-globin from precipitating in solution and live cells. AHSP knock‐out mice show ineffective erythropoiesis and pathological features similar to those of β‐thalassaemia and loss of AHSP exacerbates the haematological abnormalities in β‐thalassaemic mice. AHSP is highly expressed in erythroid precursors and its expression is most abundant during late‐stage erythroid maturation. AHSP gene dosage would modulate pathologic states of alpha-globin excess such as beta-thalassaemia.
