Protein Domain : CKK domain superfamily IPR038209

Type	Homologous_superfamily
Description	The CKK domain occurs at the C terminus of a family of proteins collectively defined as calmodulin-regulated spectrin-associated (or CAMSAP) proteins. CAMSAP proteins carry an N-terminal region that includes a CH domain, a central region including a predicted coiled-coil, and this C-terminal CKK domain which is involved in binding CAMSAP proteins to microtubules [ ].The structure of the CKK domain is a β-barrel with an associated α-helical hairpin. Characteristically, the CKK domain has a single invariant tryptophan residue within the core of the predicted β-barrel. Residues that interact with this Trp to form part of this core are highly conserved too.
