|---|---|
| Other Names | Sperm-egg fusion protein Juno, Folate receptor 4, Folate receptor delta, FR-delta, IZUMO1 receptor protein JUNO, IZUMO1R (HGNC:32565), FOLR4, JUNO |
| Target/Specificity | This FOLR4 antibody is generated from rabbits immunized with a KLH conjugated synthetic peptide between 17-46 amino acids from the N-terminal region of human FOLR4. |
| Dilution | WB~~1:1000 E~~Use at an assay dependent concentration. |
| Format | Purified polyclonal antibody supplied in PBS with 0.09% (W/V) sodium azide. This antibody is purified through a protein A column, followed by peptide affinity purification. |
| Storage | Maintain refrigerated at 2-8°C for up to 2 weeks. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles. |
| Precautions | FOLR4 Antibody (N-term) is for research use only and not for use in diagnostic or therapeutic procedures. |
| Name | IZUMO1R (HGNC:32565) |
|---|---|
| Function | Receptor for IZUMO1 present at the cell surface of oocytes (oolemma), which is essential for species-specific gamete recognition and fertilization. The IZUMO1:IZUMO1R/JUNO interaction is a necessary adhesion event between sperm and egg that is required for fertilization but is not sufficient for cell fusion (PubMed:30517645). The ligand- receptor interaction probably does not act as a membrane 'fusogen'. Does not bind folate. |
| Cellular Location | Cell membrane; Lipid-anchor, GPI-anchor {ECO:0000250|UniProtKB:Q9EQF4}. Cell projection, microvillus membrane; Lipid- anchor, GPI-anchor {ECO:0000250|UniProtKB:Q9EQF4}. Note=GPI-anchored at the oolemma microvilli. {ECO:0000250|UniProtKB:Q9EQF4} |
| Tissue Location | Expressed in unfertilized oocytes (at protein level). |

Foundational characteristics of cancer include proliferation, angiogenesis, migration, evasion of apoptosis, and cellular immortality. Find key markers for these cellular processes and antibodies to detect them.
The SUMOplot™ Analysis Program predicts and scores sumoylation sites in your protein. SUMOylation is a post-translational modification involved in various cellular processes, such as nuclear-cytosolic transport, transcriptional regulation, apoptosis, protein stability, response to stress, and progression through the cell cycle.
The Autophagy Receptor Motif Plotter predicts and scores autophagy receptor binding sites in your protein. Identifying proteins connected to this pathway is critical to understanding the role of autophagy in physiological as well as pathological processes such as development, differentiation, neurodegenerative diseases, stress, infection, and cancer.
