A new technique of direct binding of radioactive DNA was used to screen a complementary DNA expression library from the BJAB cell line in lambda gt11 phage to derive molecular cDNA clones representing a putative B lymphocyte - specific
octamer binding protein.
Thus, this cDNA derives from a gene (oct - 2) that specifies
an octamer binding protein expressed preferentially in B lymphocytes, proving that, for at least one gene, a cell - specific transcription factor exists and its amount is controlled through messenger RNA availability.

Center cells lost the expression of
octamer -
binding transcription factor 4 (OCT4) and epithelial cadherin (E-cadherin) faster than perimeter cells, which are critical to the development of heart tissue.
Oct4 contains two distinct DNA
binding domains (the POUH and POUS domains, each of which can
bind to half of the DNA
octamer motif independently of the other) which are separated by a flexible linker [39]; this in turn allows for substantial leeway in arrangement of these domains in relation to each other [17].
Oct4 has two distinct DNA
binding domains which independently
bind half - sites of the canonical
octamer motif.
