This entry represents the N-terminal domain of the SAS-6 centriolar protein, both in C.elegans and in humans. The N-terminal domain is the region through which the 9 rod-shaped homodimers that SAS-6 forms on oligomerisation interact with each other. Proper functioning of the centriole requires this correct oligomerisation [1].	Domain

This entry represents the C-terminal coiled-coil (CC) domain found in Spindle assembly abnormal protein 6 homolog from Drosophila melanogaster (Sas-6) and similar sequences found predominantly in arthropods. Sas-6 is a central scaffolding component of the centrioles ensuring their nine-fold symmetry. Sas-6 forms a dimer through this domain to then further homo-oligomerise to form a ring structure from which the CC domains emanate as spokes [1].	Domain
