Medical Definition of Septin
1.
Family of homologous proteins (around 40 kD) first identified in Saccharomyces cerevisiae where they associated with cytokinesis and septum formation. Encoded by CDC3, CDC10, CDC11 and CDC12 genes in s. Cerevisiae: seem to form 10nm filaments that form a ring around the plasma membrane in the mother bud neck. Homologous proteins, associated with cleavage furrows, are reported from Drosophila, amphibians and mammals. Mol Biol Cell 6: 1843
