Kinesin
A family of microtubule motor proteins active in mitosis. The kinesins use chemical energy from the hydrolysis of ATP (adenosine triphosphatase) to generate mechanical force. They bind tightly to and move along the microtubules. The kinesins are not related in sequence to the other known class of microtubule motor proteins, the dyneins.

- Kingella kingae
A type of bacteria that has emerged from obscurity to become known as an important cause of invasive infections in young children. These infections include especially septic arthritis (infection of joints), osteomyelitis (infection of bone), spondylodiscitis (infection of the spine and discs), bacteremia (infection of the bloodstream), and endocarditis (infection of the heart valves). Less […]
- Kinome
A subset of the genome consisting of the protein kinase genes. The complete complement of over 500 protein kinases constitutes one of the largest of all human gene families. Protein kinases act as key regulators of cell function by catalyzing (facilitating) the addition of a negatively charged phosphate group to proteins. This process of protein […]
