|Application ||WB, IHC-P, IF, IP|
|Reactivity||Human, Mouse, Rat, Monkey|
|Dilution||IHC-P (1:50), WB (1-2 µg/ml),|
|Other Names||Progesterone receptor, PR, Nuclear receptor subfamily 3 group C member 3, PGR, NR3C3|
|Target/Specificity||Equally recognizes two proteins: 116kD (triplet) and 81kD (singlet) which are identified as the hormone-binding high (B) and low (A) MW forms of human progesterone receptor. This antibody recognizes an epitope in the N-terminal half o human PgR. Spec ...|
|Reconstitution & Storage||May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for at least 12months.|
|Precautions||PR / Progesterone Receptor Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||The steroid hormones and their receptors are involved in the regulation of eukaryotic gene expression and affect cellular proliferation and differentiation in target tissues. Depending on the isoform, progesterone receptor functions as transcriptional activator or repressor.|
|Cellular Location||Nucleus. Cytoplasm. Note=Nucleoplasmic shuttling is both homone- and cell cycle-dependent. On hormone stimulation, retained in the cytoplasm in the G(1) and G(2)/M phases Isoform 4: Mitochondrion outer membrane|
|Tissue Location||In reproductive tissues the expression of isoform A and isoform B varies as a consequence of developmental and hormonal status. Isoform A and isoform B are expressed in comparable levels in uterine glandular epithelium during the proliferative phase of the menstrual cycle. Expression of isoform B but not of isoform A persists in the glands during mid-secretory phase. In the stroma, isoform A is the predominant form throughout the cycle. Heterogeneous isoform expression between the glands of the endometrium basalis and functionalis is implying region- specific responses to hormonal stimuli|

The steroid hormones and their receptors are involved in the regulation of eukaryotic gene expression and affect cellular proliferation and differentiation in target tissues. Progesterone receptor isoform B (PRB) is involved activation of c-SRC/MAPK signaling on hormone stimulation. Isoform 4: Increases mitochondrial membrane potential and cellular respiration upon stimulation by progesterone.
