| Short Description: |
This CUBN Sandwich ELISA is an in-vitro enzyme-linked immunosorbent assay for the measurement of samples in human cell culture supernatant, serum and plasma (EDTA, citrate, heparin). |
| Storage Instruction: |
If unopened the kit may be stored at 2-8°C for up to 1 month. If the kit will not be used within 1 month, store the components separately, according to the component table in the manual. |
| Assay Time: |
3.5h |
| Detection: |
Colormetric |
| Gene Symbol: |
CUBN |
| Gene ID: |
8029 |
| Uniprot ID: |
CUBN_HUMAN |
| Specificity: |
This kit recognizes Human CUBN in samples. No significant cross-reactivity or interference between Human CUBN and analogues was observed. |
| Sample Type: |
Serum, plasma and other biological fluids |
| Post Translational Modifications | The precursor is cleaved by a trans-Golgi proteinase furin, removing a propeptide. N-glycosylated. |
| Function | Endocytic receptor which plays a role in lipoprotein, vitamin and iron metabolism by facilitating their uptake. Acts together with LRP2 to mediate endocytosis of high-density lipoproteins, GC, hemoglobin, ALB, TF and SCGB1A1. Acts together with AMN to mediate endocytosis of the CBLIF-cobalamin complex. Binds to ALB, MB, Kappa and lambda-light chains, TF, hemoglobin, GC, SCGB1A1, APOA1, high density lipoprotein, and the CBLIF-cobalamin complex. Ligand binding requires calcium. Serves as important transporter in several absorptive epithelia, including intestine, renal proximal tubules and embryonic yolk sac. May play an important role in the development of the peri-implantation embryo through internalization of APOA1 and cholesterol. Binds to LGALS3 at the maternal-fetal interface. |
