Disease relevance of Prrx1

 

High impact information on Prrx1

 

Biological context of Prrx1

 

Anatomical context of Prrx1

  • Our data reveal that the prx1 limb enhancer is proximally located within the prx1 gene and suggest that prx1 may have an autoregulatory function in limb mesenchyme [1].
  • Mice that lack both Prx1 and Prx2 functions display reduction or absence of skeletal elements in the skull, face, limbs and vertebral column [6].
  • This analysis showed that a conserved domain (PRX), found in both Prx1 and Prx2, activated transcription in NIH 3T3 cells [10].
  • However, the Prx1-/- and Prx1/Prx2 double-null mutants showed a vascular abnormality with an abnormal positioning and awkward curvature of the aortic arch in addition to a misdirected and elongated ductus arteriosus, and in two of seven combined mutants, an anomalous retro-oesophageal right subclavian artery [9].
  • Initial studies revealed that Prx1 localizes to differentiating endothelial cells (ECs) within the fetal lung mesenchyme, and later within ECs forming vascular networks [11].
 

Associations of Prrx1 with chemical compounds

  • Evidence is provided that this increase of fibrin binding is mediated by the kringle 2 (K2) domain that contains a lysine-binding site [12].
  • The k1 value for tcwt-rtPA was not influenced by the presence of epsilon-aminocaproic acid, suggesting that the lysine-binding site associated with the kringle 2 (K2) region of tPA does not modulate the rate of its initial interaction with rPAI-1 [13].
  • This localization strongly suggests that CLC-K2 confers the basolateral conductance in the type A intercalated cells where Cl(-) is taken up by the anion exchanger in exchange for HCO(3)(-) at the basolateral membranes [14].
  • CLC-K2, a kidney-specific member of the CLC chloride channel family, is thought to play an important role in the transepithelial Cl(-) transport in the kidney [14].
  • These results suggest that a novel set of zinc finger proteins may help regulate the strict tissue and nephron segment-specific expression of CLC-K1 and CLC-K2 channel genes through their GA cis element [15].
