Introduction

This is a sample scene created with SAT to by Group, and another to make of the protein.

Overall Structure

-Monomeric

-Glycogen Synthase Kinase-3 (GSK-3) is a serine/threonine protein kinase

-2 isoforms: alpha and beta, that are 97% homologous in their catalytic domain, but diverse at the N and C terminus.

-Both isoforms have a conserved N-terminal serine reside (S21 for alpha and S9 for beta)

-Phosphorylation of the N-terminal serine residue plays an important role for further activity

-Classified the PDB structures into three groups
