    basic FUNCTION having prolyl 3-hydroxylase activity catalyzing the posttranslational formation of 3-hydroxyproline
    in -Xaa-Pro-Gly- sequences in collagens, especially types IV and V
  • tissue specific P3H1, P3H2, P3H3 gene expression in both fetal and adult tissues indicating a developmental role for prolyl 3-hydroxylase activity
  • is a novel tumor suppressor and its protein expression is inversely related to lymph node metastasis and tumor differentiation in lung cancer
  • is involved in the post-translational modification of fibrillar collagens
  • role for the Leprecans in the post-translational modification of collagens expressed in the stroma of the reproductive organs
