Cat member of the cat family, the felids, which are a rapidly evolving family of mammals that share a common ancestor only 10–15 million years ago and include lions, tigers, cougars and many others. Within this family, domestic cats ("Felis catus") are part of the genus "Felis", which is a group of small cats containing about seven species (depending upon classification scheme). Members of the genus are found worldwide and include the jungle cat ("Felis chaus") of southeast Asia, European wildcat ("F. silvestris silvestris"), African wildcat ("F. s. lybica"), the Chinese mountain cat ("F. bieti"), and the Arabian sand cat ("F.
Kinesin family member 11 Kinesin family member 11 Kinesin-5 is a molecular motor protein that is essential in mitosis. Kinesin-5 proteins are members of kinesin superfamily, which are nanomotors that move along microtubule tracks in the cell. Named from studies in the early days of discovery, it is also known as kinesin family member 11, encoded by the KIF11 gene, or as BimC, Eg5 or N-2, based on the founding members of this kinesin family. The term kinesin-5 has been recommended based on a standardized nomenclature adopted by the scientific community. Currently, there are over 70 different eukaryotic kinesin-5 proteins identified by sequence similarity.
