The CDK4 gene is located on chromosome 12 in humans. [7] The gene is composed of 4,583 base pairs which together code for the 303 amino acid protein with a molecular mass of 33,730 Da. [7] [8] All CDK proteins, including CDK4, have two lobes: the smaller N-terminal lobe (which contains an inhibitory G-loop), and the C terminal lobe (which contains an activation domain and a T-loop).
Without cyclin, CDK is less active than in the cyclin-CDK heterodimer complex. [ 5 ] [ 6 ] CDKs phosphorylate proteins on serine (S) or threonine (T) residues. The specificity of CDKs for their substrates is defined by the S/T-P-X-K/R sequence, where S/T is the phosphorylation site, P is proline, X is any amino acid, and the sequence ends with ...
In CDK-cyclin complexes, this activation region is composed of a conserved αL-12 Helix and contains a key phosphorylatable residue (usually Threonine for CDK-cyclin partners, but also includes Serine and Tyrosine) that mediates the enzymatic activity of the CDK. It is at this essential residue (T160 in CDK2 complexes, T177 in CDK6 complexes ...

CDK is a library written in C that provides a collection of widgets for text user interfaces (TUI) development. The widgets wrap ncurses functionality to make writing full screen curses programs faster. Perl [1] [2] and Python [3] bindings are also available. There are two versions of the library.
