LCoR in MCF‑7 Human Cell Line. LCoR was detected in immersion fixed MCF‑7 human breast cancer cell line using Mouse Anti-Human LCoR Monoclonal Antibody (Catalog # MAB7534) at 25 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red, upper panel; Catalog # NL007) and counterstained with DAPI (blue, lower panel). Specific staining was localized to nuclei. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

LCoR (ligand-dependent corepressor), also known as MLR2 (Mblk1-related protein 2), is a 47-50 kDa nuclear phosphoprotein that is a corepressor of ligand-dependent transcriptional activation by nuclear receptors such as estrogen and progesterone receptors. It is widely expressed throughout fetal development and in the adult. The 433 amino acid (aa) LCoR contains two N-terminal PxDLS nuclear receptor interaction motifs, a central HDAC interaction motif, a nuclear localization signal, and a C‑terminal Helix-Turn-Helix motif. Alternate splicing produces a truncated 406 aa variant. Within the region used as an immunogen, human LCoR shares 97% aa identity with mouse and rat LCoR.
