  • Target

    • Function
      Transcription factor involved in developmental processes such as cell fate determination, gene transcriptional regulation and progenitor cell regulation in a number of organs. Plays a critical role in embryonic development and functions as a key regulatory protein in neurogenesis and the development of the heart, eye lens, liver, pancreas and the lymphatic system. Involved in the regulation of the circadian rhythm. Represses: transcription of the retinoid-related orphan receptor RORG, transcriptional activator activity of RORA and RORG and the expression of RORA/G-target genes including core clock components: ARNTL/BMAL1, NPAS2 and CRY1 and metabolic genes: AVPR1A and ELOVL3.
    • Tissue specificity
      Most actively expressed in the developing lens. Detected also in embryonic brain, lung, liver and kidney. In adult, it is more abundant in heart and liver than in brain, skeletal muscle, kidney and pancreas.
    • Sequence similarities
      Belongs to the Prospero homeobox family.
      Contains 1 Prospero-type homeobox DNA-binding domain.
    • Domain
      The prospero-type homeobox DNA-binding domain is essential for repression of RORG transcriptional activator activity.
    • Cellular localization
      Nucleus. RORG promotes its nuclear localization.
    • Information by UniProt
    • Database links
    • Form
      Prox1 is a specific and required regulator of the development of the lymphatic system and that the vascular and lymphatic systems develop independently. Sox18 directly activates Prox1 transcription by binding to its proximal promoter.

    Je tiens à vous informer que le laboratoire n'a pas non plus pu retrouver la réactivité contre la souris et nous allons donc enlever ceci de notre fiche technique. Nous allons aussi informer les clients concernés.
