Abstract

The CaMK subfamily of Ser/Thr kinases are regulated by calmodulin interactions with their C-terminal regions. They are exemplified by Ca²⁺/calmodulin dependent protein kinase 1δ which is known as CaMK1D, CaMKIδ or CKLiK. CaMK1D mediates intracellular signalling downstream of Ca²⁺ influx and thereby exhibits amplifications of Ca²⁺signals and polymorphisms that have been implicated in breast cancer and diabetes. Here we report the backbone ¹H, ¹³C, ¹⁵N assignments of the 38 kDa human CaMK1D protein in its free state, including both the canonical bi-lobed kinase fold as well as the autoinhibitory and calmodulin binding domains.

Keywords: CKLiK; CaMK1D; CaMKIδ; Calcium/calmodulin dependent protein kinase; NMR; Protein resonance assignment.
