gene In biology, the word gene (from , ; "... Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a b ...

. This gene encodes a member of the ancient conserved domain containing protein family. Members of this protein family (CNNM1, CNNM2, CNNM3 and CNNM4) contain a cyclin box motif and have structural similarity to the

cyclins Cyclin is a family of proteins that controls the progression of a cell through the cell cycle by activating cyclin-dependent kinase (CDK) enzymes or group of enzymes required for synthesis of cell cycle. Etymology Cyclins were originally di ...
