SP1/2/3 and NfY cooccurency in MEFs

ABSTRACT: Investigation of the binding behaviour of Sp1, Sp2, Sp3 and NF-ya, NF-yb and NF-yc in mouse embryonic fibroblasts and of Sp1, Sp2 and Sp3 in HEK-293 cells reveals distinct binding of the seemingly similar transcription factors Sp1/3 and Sp2.

Transcription factors are grouped into families based on sequence similarity within functional domains, particularly DNA-binding domains. The Specificity proteins Sp1, Sp2 and Sp3 are paradigmatic of closely related transcription factors. They share amino-terminal glutamine-rich regions and a conserved carboxy-terminal zinc finger domain that can bind to GC rich motifs in vitro. All three Sp proteins are ubiquitously expressed; yet they carry out unique functions in vivo raising the question of  ...[more]
