Structure
Human NANOG protein is a 305 amino acid protein with a conserved homeodomain motif that is localized to the nuclear component of cells. The homeodomain region facilitates DNA binding.
There are N-terminal, homeodomain, and C-terminal regions in human NANOG protein. Like murine NANOG, the N-terminal region of human NANOG is rich in Ser, Thr and Pro residues, and the C-terminus contains W repeats. The homeodomain in hNANOG ranges from residues 95 to 155. The conserved sequence of homeodomain are a.a. 99-100, 102, 106-107, 110, 114, 119, 121, 127-128, 132, 134, 138-140, 142-145, 147, 149, and 151-152.

Famous quotes containing the word structure:
“A special feature of the structure of our book is the monstrous but perfectly organic part that eavesdropping plays in it.”
—Vladimir Nabokov (1899–1977)
“There is no such thing as a language, not if a language is anything like what many philosophers and linguists have supposed. There is therefore no such thing to be learned, mastered, or born with. We must give up the idea of a clearly defined shared structure which language-users acquire and then apply to cases.”
—Donald Davidson (b. 1917)
“Science is intimately integrated with the whole social structure and cultural tradition. They mutually support one other—only in certain types of society can science flourish, and conversely without a continuous and healthy development and application of science such a society cannot function properly.”
—Talcott Parsons (1902–1979)
