一般描述

The neurophysin 1 and 2 (NPI and NPII) are carriers of peptide hormons oxytocin (OT) and vasopressin (AVP), respectively. Each NP and its associated hormon peptide are synthesized as one precursor protein, OT-NPI (UniProt P01179) encoded by the Oxt (or Ot) gene or AVP-NPII (UniProt P01186) encoded by the Avp gene in rat species. Posttranslational cleavages remove the signal peptide and process the precursor into mature OT and NPI (aa 20-28 and aa 32-135, respectively, of OT-NPI), or AVP and NPII (aa 24-32 and aa 36-128, respectively, of AVP-NPII). OT is a potent hormone and neurotransmitter secreted within the pituitary gland. OT exerts its biological activity through its receptor OXTR (also known as OTR). OT is used clinically for labor induction and may exhibit therapeutic potential for treating social anxiety disorders. AVP functions primarily as an antidiuretic and regulates the concentration of water, glucose, and salts in blood. AVP is secreted from the posterior pituitary, but exerts its biological activity in the kidney via the G protein-coupled receptor AVPR2 (V2R).

应用

Immunohistochemistry Analysis: A 1:250-1,000 dilution from a representative lot detected Neurophysin 2/NP-AVP in rat brain and rat pituitary tissue.
Radioimmunoassay (RIA): Target specificity of a representative lot was confirmed by RIA. Only rat neurophysin 2, but not neurophysin 1, oxytocin, or angiotensin II, can compete against 125I-neurophysin 2 for binding mAb PS 45 (Ben-Barak, Y., et al. (1985). J Neurosci. 5(1):81-97).
Electron Microscopy (EM): A representative lot immunostained granulated neurosecretory vesicles (NSVs) in all axons, Herring bodies, and terminals by EM using rat posterior pituitary LR White sections (Ben-Barak, Y., et al. (1985). J Neurosci. 5(1):81-97).
Immunoprecipitation Analysis: A representative lot immunoprecipitated radiolabelled neurophysin 2, but not neurophysin 1 (Ben-Barak, Y., et al. (1985). J Neurosci. 5(1):81-97).
ELISA Analysis: A representative lot detected neurophysin 2 immunoreactivity in rat neurophysin preparations by non-sandwich ELISA using either 125I-labelled or HRP-conjugated secondary antibody (Ben-Barak, Y., et al. (1985). J Neurosci. 5(1):81-97).

This Anti-Neurophysin 2/NP-AVP Antibody, clone PS 45 is validated for use in Western Blotting, Immunohistochemistry (Paraffin), Radioimmunoassay, Electron Microscopy, Immunoprecipitation, ELISA for the detection of Neurophysin 2/NP-AVP.

生化/生理作用

Clone PS 45 reacts with Vasopressin-neurophysin 2-copeptin precursor, neurophysin 2, but not Arg-vasopressin, copeptin, oxytocin, or neurophysin 1.

Characterization of Estrogen Receptor α Phosphorylation Sites in Breast Cancer Tissue Using the SNAP i.d® 2.0 System

A major focus of breast cancer research is to understand the mechanisms responsible for disease progression and drug resistance. Toward that end, it has been found that approximately two thirds of all human breast carcinomas overexpress the Estrogen Receptor α (ERα) protein and it remains the primary pharmacological target for endocrine therapy1,2. The normal cellular function of ERα is as a transcription factor that mediates a wide variety of physiological processes, many of which are dependent upon phosphorylation of the receptor at specific amino acid residues3,4. Indeed, ERα is known to be phosphorylated at a multitude of different sites, yet how these all correlate to disease remains unclear5. Here, we interrogated multiple sites of ERα for phosphorylation status by screening an extensive panel of different breast cancer patient samples and other non-breast cancer tissue microarray (TMA) slide samples to determine their relevance to disease.
