Product Details

PAH polyclonal antibody CSB-PA017396LA01HU was produced in the rabbit immunized by using the Recombinant Human Phenylalanine-4-hydroxylase protein (2-452AA) as the immunogen. The target protein PAH, a phenylalanine hydroxylase enzyme, hydroxylates phenylalanine to tyrosine and is the rate-limiting step in phenylalanine catabolism. This protein can catalyze the hydroxylation of L-phenylalanine to L-tyrosine. Diseases associated with PAH include Phenylketonuria and Mild Hyperphenylalaninemia.
This Rabbit anti-Homo sapiens (Human) PAH Polyclonal antibody was tested in the ELISA, WB, IHC and IF applications. The non-conjugated IgG got purified by protein G and reached up to 95% in purity. It reacts with the PAH proteins of human or mouse-origin and may be used to detect the endogenous levels of PAH protein.

  6. Report a novel intron 11 regulatory element, which is involved in exon 11 splicing, as revealed by the investigated pathogenic effect of variants c.1199+17G>A and c.1199+20G>C, identified in PKU patients. Both mutations cause exon 11 skipping in a minigene system. PMID: 29684050
  7. three novel variants of the PAH gene, p.E178K (c.532G>A), p.V245M (c.733G>A), p.S250F (c.749C>T), showed impaired protein expression and enzyme activity. PMID: 29653233

Study found no correlation between autism and mutations affecting the phenylalanine hydroxylase gene, but the age of die PMID: 26759449
  9. Studies involving co-expression of differently phenylalanine hydroxylase (PAH) alleles have shown that one variant form can influence the other when assembled into a tetramer and have effect on enzyme activity in vitro, and on BH4 responsiveness and PKU phenotype in patients carrying them. [review] PMID: 26919687
  10. 17 VUS (37%; 7 in ACADM, 9 in GALT, and 1 in PAH) were reclassified from uncertain (6 to benign or likely benign and 11 to pathogenic or likely pathogenic).

  20. The co-expression of two distinct PAH variants revealed possible dominance effects (positive or negative) by one of the variants on residual PAH activity as a result of interallelic complementation. PMID: 26803807
  21. PAH gene mutation analysis combined with STR linkage analysis can provide rapid and accurate prenatal diagnosis for phenylketonuria families PMID: 26600521
