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

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. -

Western blot - Anti-PROX1 antibody (ab38692)All lanes : Anti-PROX1 antibody (ab38692) at 1 µg/ml (3% Milk Block)
Lane 1 : HepG2 (Human) Whole Cell Lysate (ab52257)
Lane 2 : SHSY-5Y (Human neuroblastoma cell line) Whole Cell Lysate (ab45968)
Lane 3 : HEK293 (Human) Whole Cell Lysate (ab52256)
Lysates/proteins at 10 µg per lane.
Secondary
All lanes : Goat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97080) at 1/10000 dilution
Developed using the ECL technique.
Performed under reducing conditions.
Predicted band size: 83 kDa
Observed band size: 95 kDa why is the actual band size different from the predicted?
Additional bands at: 25 kDa. We are unsure as to the identity of these extra bands.
Exposure time: 4 minutes -
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-PROX1 antibody (ab38692)Formaldehyde-fixed, paraffin-embedded human heart tissue stained for PROX1 using ab38692 at 1/250 dilution in immunohistochemical analysis. Incubation with primary antibody was performed for 45 minutes at 20°C. Goat anti-rabbit/mouse HRO polymer was used as a secondary antibody.
Heat mediated antigen retrieval was performed. Tissue sections were blocked with peroxidase for 5 minutes followed by a 10 minute protein block.
