Unc-51-like kinase 2 (C. elegans) also known as ULK2 is an enzyme which in humans is encoded by the ULK2 gene. The gene is located within the Smith-Magenis syndrome region on chromosome 17. Unc-51-like kinase 2 (C. elegans) also known as ULK2 is an enzyme which in humans is encoded by the ULK2 gene. The gene is located within the Smith-Magenis syndrome region on chromosome 17. This gene encodes a protein that is similar to a serine/threonine kinase in C. elegans which is involved in axonal elongation. The structure of this protein is similar to the C. elegans protein in that both proteins have an N-terminal kinase domain, a central proline/serine rich (PS) domain, and a C-terminal (C) domain. ULK2 and the GTPase activating protein SynGAP function cooperatively in axon formation.
