dominio de dedos de zinc y poxvirus
Scope note: Dominio de interacción con proteínas que participa en la homodimerización presente en el extremo N-terminal de la proteínas y que tiene varias copias de los DEDOS DE CINC CYS2-HIS2 o de las REPETICIONES KELCH. Se caracterizan por presentar dímeros fuertemente entrelazados con una extensa interfaz hidrofóbica. En la interfaz del dímero se forma un surco superficial expuesto que se encuentra alineado con aminoácidos conservados, lo que sugiere un lugar de unión a péptidos. Muchas proteínas BTB son reguladores transcripcionales y se cree que regulan las estructuras de CROMATINA.

Scope note: A homodimerization protein interaction domain occurring at the N terminus of proteins that contain multiple copies of either CYS2-HIS2 ZINC FINGERS or KELCH REPEATS. It is characterized by a tightly intertwined dimer with an extensive hydrophobic interface. A surface-exposed groove lined with conserved amino acids is formed at the dimer interface, suggesting a peptide-binding site. Many BTB proteins are transcriptional regulators that are thought to regulate CHROMATIN structure.
