Scope note: Dominios de proteínas altamente conservados de unos 130 a 140 aminoácidos. El dominio SET se identificó por primera vez en las proteínas de Drosophila (S)u(var)3-9, (E)nhancer-of-zeste y (T)rithorax y se encuentra también en otras proteínas con diversas funciones como la histona-lisina N-metiltransferasa. Constan de LÁMINAS BETA intercaladas entre bucles y giros que resultan en una forma de "L". Los motivos más conservados son un tramo en el extremo C-terminal que contiene un residuo de tirosina estrictamente conservado y un bucle adyacente por el que pasa el segmento C-terminal formando un "nudo". Estos motivos, y especialmente el residuo de tirosina, son esenciales para la unión y catálisis de la S-ADENOSILMETIONINA. El dominio PR tiene una alta homología con la región catalítica del dominio SET y se encuentra en el extremo N-terminal de las proteínas PRDM como la PROTEÍNA PRDM1.

Scope note: Highly conserved protein domains of approximately 130 to 140 amino acids. The SET domain was first identified in the Drosophila proteins (S)u(var)3-9, (E)nhancer-of-zeste and (T)rithorax and occurs in other proteins with a variety of functions, including histone-lysine N-methyltransferases. Structurally, it consists of BETA-SHEETS interspersed among loops and turns that result in an "L" shape. The most conserved motifs are a stretch at the C-terminal that contains a strictly conserved tyrosine residue and an adjacent loop that the C-terminal segment passes through to form a "knot". These motifs and especially the tyrosine residue are essential for S-ADENOSYLMETHIONINE binding and catalysis. The PR domain has high homology to the catalytic region of the SET domain and occurs at the N-terminal of PRDM proteins such as PRDM1 PROTEIN.
