[Haskell-cafe] Relations between Functor typeclass and kind

Hi all, Some days ago, I was talking with someone about Kinds and GADTs. At some point he mention that types with this Kind: (* -> *) are called Functors. So, is there any relations between Functor typeclass and Functor kind? Is it considered as a "pattern"? if so, are there some other ones? If you have any link on this, I'll take them. Thanks in advance for your help.
