Target

  • Function

    Corepressor targeting diverse transcription regulators. Functions in brown adipose tissue (BAT) differentiation.
    Isoform 2 probably acts as a scaffold for specialized synapses.

  • Tissue specificity

    Ubiquitous. Highest levels in heart, skeletal muscle, and pancreas.

  • Sequence similarities

    Belongs to the D-isomer specific 2-hydroxyacid dehydrogenase family.

  • Post-translational
    modifications

    Isoform 2 is phosphorylated upon DNA damage, probably by ATM or ATR at Thr-179; Ser-181 and Ser-185. Phosphorylation by HIPK2 on Ser-428 induces proteasomal degradation.

  • Cellular localization

    Nucleus. Cell junction > synapse.

    Immunocytochemistry analysis of SH-SY5Y (Human neuroblastoma epithelial cell) cells labeling CTBP2 with purified ab128871 at 1:50 dilution (2.5 µg/ml). Cells were fixed in 4% Paraformaldehyde and permeabilized with 0.1% tritonX-100. Cells were counterstained with Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) at 1/200 dilution (2.5 µg/ml) (ab195889) (red). Goat anti-rabbit IgG (Alexa Fluor® 488) (ab150077) was used as the secondary antibody at 1:1000 (2 µg/ml) dilution. DAPI (blue) was used as a nuclear counterstain. PBS instead of the primary antibody was used as the secondary antibody only control.

Heat mediated antigen retrieval was performed using Bond™ Epitope Retrieval Solution 2 (pH 9.0). Tissue was counterstained with Hematoxylin. LeicaDS9800 (BondTM Polymer Refine Detection) was used at 1:0 dilution. PBS instead of the primary antibody was used as the negative control. The immunostaining was performed on a Leica Biosystems BOND® RX instrument.
