The prolyl 4-hydroxylase, alpha polypeptide III ELISA kits listed below are analytical tools for measuring concentrations of prolyl 4-hydroxylase, alpha polypeptide III in various samples. prolyl 4-hydroxylase, alpha polypeptide III is an alternative name for the human P4HA3 gene, which encodes the protein, prolyl 4-hydroxylase subunit alpha 3. The target protein is known to catalyze the post-translational formation of 4-hydroxyproline in -Xaa-Pro-Gly- sequences in collagens and other proteins. Structurally, the P4HA3 protein is 544 amino acid residues in length and 61.1 kilodaltons in mass. However, as many as 3 protein isoforms have been identified. It is localized to the ER of the cell. In terms of tissue specificity, it is reported to be highly expressed in placenta, liver and fetal skin. This protein is known to be N-glycosylated. Other names for this target antigen include 4-PH alpha-3, C-P4H alpha III, and collagen prolyl 4-hydroxylase alpha(III).
