Target
-
Function
Single stranded DNA-binding protein, with specificity to the sterol regulatory element (SRE). Involved in sterol-mediated repression. -
Tissue specificity
Present in all tissues examined. -
Involvement in disease
Defects in CNBP are the cause of dystrophia myotonica type 2 (DM2) [MIM:602668]; also known as proximal myotonic myopathy (PROMM). A multisystem disease characterized by the association of proximal muscle weakness with myotonia, cardiac manifestations and cataract. Additional features can include hyperhidrosis, testicular atrophy, insulin resistance and diabetes and central nervous system anomalies in rare cases. Note=The causative mutation is a CCTG expansion (mean approximately 5000 repeats) located in intron 1 of the CNBP gene. -
Sequence similarities
Contains 7 CCHC-type zinc fingers. -

Immunocytochemistry/ Immunofluorescence - Anti-CNBP antibody (ab48027)ICC/IF image of ab48027 stained MCF-7 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA, 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab48027 at 5µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 donkey anti- goat (ab96931) IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
