CSNK1A1 and infection: Future research will have (i) to expand knowledge on their biological functions in the parasite for instance by screening for their binding partners and substrates (Tables 2 and 3); (ii) to elucidate the mechanism of CK1 release into the host environment, as well as their role in immune and metabolic host subversion; and (iii) to determine mechanisms underlying CK1-mediated and infection-related aspects of host-parasite interactions, both for intra- and extracellular parasites.
