Kinase Family RCK
Both subfamilies are found throughout eukaryotes, though MOK is lost in several lineages that have also lost cilia.
All RCK kinases have an N-terminal kinase domain and a variable length (~100-300 AA) C-terminal tail without any known domains. Almost all RCK kinases have a T[DE]Y motif in their activation loop, similar to MAPK, and require both the T and Y to be phosphorylated for complete function.
MAK and MOK subfamilies are implicated in cilia biology, with MAK also being involved in meiosis.
The family is named RCK after the mouse gene rck, the ortholog of human MAK. It was defined in the 2002 human kinome paper Manning, along with the MAK and MOK subfamilies.
