“…Because of the marked heatsensitivity of the protein interacting with the rGH silencer-1 element (data not shown), it is unlikely that it corresponds to C/EBP. In addition, since both the precise sequences required for binding and the methylation interference footprints observed with NF1 differ from those of C/EBP (44) and the heterodimeric proteins (41,45), it is unlikely that the rGH silencer-l binding protein belongs to either of these classes. Even less well defined is the reported interaction of a subset of modified histone Hl proteins with NFl sites (46).…”

“…(i) EMSA competition experiments with the original Ea Y box oligo or with other bona fide high affinity NF-Y binding sites such as α1(I) collagen, albumin, α-globin, RSV or MLP (21,22,51). The albumin promoter was shown to function through a NF-Y binding CCAAT box (50); a trimeric complex was purified to homogeneity on α-globin CCAAT affinity columns; subunit composition and sequence specificities are indistinguishable from NF-Y (23); the RSV and MLP CCAAT proteins also shared these features (51,52). (ii) Direct supershift experiments with anti-NF-Y antibodies.…”

“…Δεδομένου ότι οι πρωτείνες hCSDA και DbpB αναγνωρίζουν με μεγαλύτερη συγγένεια μονόκλωνο DNA αυτής της περιοχής και έχει δειχτεί στην περίπτωση του υποκινητή των γονιδίων DRA (MacDonald et al, 1995) ότι τουλάχιστον ο παράγοντας ΥΒ-1/DbpB μπορεί να σταθεροποιεί τη δομή Η-DNA, είναι πιθανό, ο σχηματισμός μιας τέτοιας δομής στον υποκινητή της α-σφαιρίνης και η σταθεροποίηση της μέσω της πρόσδεσης των παραγόντων hCSDA και DbpB ή και άλλων πρωτεϊνών της οικογένειας των "Cold Shock Domain" οι οποίες δεν έχουν ακόμα ταυτοποιηθεί, να συμβάλλει στην αρνητική ρύθμιση των γονιδίων της α-σφαιρίνης στα αναπτυξιακά στάδια που τα γονίδια αυτά καταστέλλονται.

Παρατηρήθηκε ότι σχηματίζονται σε περιοχές 5' και 3' γονιδίων και πιθανολογείται ότι παίζουν ρόλο στην καταστολή της γονιδιακής έκφρασης στο επίπεδο της μεταγραφής (Lu and Feri, 1993;Michel et al, 1993).…”
