Background: CTCF

The vertebrate insulator protein, CCCTC binding factor (CTCF) is a highly conserved, ubiquitously expressed DNA-binding protein that has widespread capabilities in gene regulation. CTCF contains 11 zinc finger motifs and it is thought that CTCF uses different combinations of zinc fingers to recognise a variety of specific sequences on the DNA to control several important genes. CTCF plays dual roles in cell growth regulatory processes and epigenetic functions. CTCF is a negative regulator of cell proliferation and is located in a region of the chromosome that is frequently deleted in human cancers. The CTCF protein is altered in some breast and prostate tumours. Substitutions from one amino acid to another in the DNA-binding domain change the whole spectrum of the genes regulated by CTCF which can result in cancer development. CTCF was first identified as one of the nuclear factors binding to the regulatory regions of the c-myc gene. Further study of this protein revealed roles in transcriptional repression, insulator function, and imprinting genetic information. Among the multitude of normal CTCF functions, its involvement in partitioning the genome into active or inactive domains by means of a chromatin insulator function has received particular attention. As an insulator CTCF helps to define the boundaries between the neighbouring genes. Strikingly, all vertebrate chromatin insulators identified so far interact with CTCF.
