Abstract
The disclosure provides compositions and methods useful for treating conditions related to Dual Leucine Zipper (DLK), e.g., neurodegenerative disorders including optic neuropathy. The disclosure provides gene constructs and vectors that regulate the activity of Dual Leucine Zipper Kinase (DLK) or Leucine Zipper Kinase (LZK). The disclosure also provides dominant negative DLK (DN-DLK) proteins that inhibit the kinase and/or signaling activity of DLK. The disclosure also provides vectors, pharmaceutical compositions, and methods of inhibiting DLK.
Claims16
An inhibitor, comprising a protein comprising a leucine zipper domain that shares at least 95% identity to SEQ ID NO:
- 1, wherein the leucine zipper domain comprises at least one substitution at one or more of the positions 391 and 393.
An inhibitor, comprising a protein comprising a leucine zipper domain that shares at least 95% identity to SEQ ID NO:
- 1, having at least one substitution, wherein said at least one substitution, individually or collectively, either (i) increases the binding affinity of the leucine zipper domain for endogenous dual leucine zipper kinase (DLK) or (ii) decreases affinity of said inhibitor for itself, compared to the corresponding protein without said at least one substitution.
