Function
DAPK-1 is a negative regulator of epidermal barrier repair and innate immune responses to wounding. Its role in epidermal tissue integrity and wound healing is established through the inhibition of epidermal microtubule stability, potentially via the negative regulation of the microtubule minus-end binding protein ptrn-1. Within the epidermis, DAPK-1 prevents the expression of specific unc-44 isoforms, likely by promoting nuclear localization of pinn-1. This, in turn, may influence the sydn-1-ssup-72-mediated regulation of alternative polyadenylation of unc-44 mRNA. DAPK-1 appears to function downstream of or in parallel to muscarinic signaling in the regulation of autophagy.
