This page has not been edited yet.
Evolution
PSK is found in holozoans (animals+choanoflagellates). It is lost from Drosophila. A mammalian-specific dupication gives rise to human PSKH1 and PSKH2. PSKH2 is lost in several lineages, and PSKH1 may be a pseudokinase in primates [1, 2]
Domain Structure
PSKs have an N-terminal myristoylation signal embedded in a short conserved domain, followed by another conserved motif and a CAMK-group kinase domain.
