| Short Description: | This human ESR2 kit is a highly sensitive in-vitro chemiluminescent immunoassay for the measurement of trace amounts of analytes. |
| 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: | Chemiluminescence |
| Gene Symbol: | ESR2 |
| Gene ID: | 2100 |
| Uniprot ID: | ESR2_HUMAN |
| Specificity: | This kit recognizes Human ER Beta in samples. No significant cross-reactivity or interference between Human ER Beta and analogues was observed. |
| Sample Type: | Serum, plasma and other biological fluids |
| Tissue Specificity | Isoform 1: Expressed in testis and ovary, and at a lower level in heart, brain, placenta, liver, skeletal muscle, spleen, thymus, prostate, colon, bone marrow, mammary gland and uterus. Also found in uterine bone, breast, and ovarian tumor cell lines, but not in colon and liver tumors. Isoform 2: Expressed in spleen, thymus, testis and ovary and at a lower level in skeletal muscle, prostate, colon, small intestine, leukocytes, bone marrow, mammary gland and uterus. Isoform 4: Expressed in the testis. Isoform 5: Expressed in testis, and at a lower level in spleen, thymus, ovary, mammary gland and uterus. Isoform 6: Expressed in testis, placenta, skeletal muscle, spleen and leukocytes, and at a lower level in heart, lung, liver, kidney, pancreas, thymus, prostate, colon, small intestine, bone marrow, mammary gland and uterus. Not expressed in brain. |
| Post Translational Modifications | Phosphorylation at Ser-87 and Ser-105 recruits NCOA1. |
| Function | Nuclear hormone receptor. Binds estrogens with an affinity similar to that of ESR1/ER-alpha, and activates expression of reporter genes containing estrogen response elements (ERE) in an estrogen-dependent manner. Isoform 2: Lacks ligand binding ability and has no or only very low ERE binding activity resulting in the loss of ligand-dependent transactivation ability. |
