This is the C-terminal domain found in Spc110 proteins. Spc110 is a spindle pole body component (SPB) protein. The N-terminus is shown to bind to gamma-tubulin small complex (g-TuSC) while this C-terminal domain is essential for calmodulin-binding. The C-terminus of Spc110 is anchored to the SPB via a conserved PACT domain [1].
