Septin - Wikipedia

Septins are P-Loop-NTPase proteins that range in weight from 30-65 kDa. Septins are highly conserved between different eukaryotic species. They are composed of a variable-length proline rich N-terminus with a basic phosphoinositide binding motif important for membrane association, a GTP-binding … See more Septins are a group of GTP-binding proteins expressed in all eukaryotic cells except plants. Different septins form protein complexes with each other. These complexes can further assemble into filaments, rings and … See more Since their discovery in S. cerevisiae, septin homologues have been found in other eukaryotic species, including filamentous fungi. Septins in filamentous fungi display a variety of different shapes within single cells, where they control aspects of filamentous See more The septin localized in the mitochondria is called mitochondrial septin (M-septin). It was identified as a CRMP/CRAM-interacting protein in the developing rat brain. See more • Güler GÖ, Mostowy S (Mar 2024).
