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
A, B, C, D	PF21503	Centriolar protein SAS, helical domain (Sas-6_helical)	Centriolar protein SAS, helical domain	This domain is found in Spindle assembly abnormal protein 6 from Caenorhabditis elegans (Sas-6), which is essential for centriole formation. This domain is C-terminal to Pfam:PF16531. It shows an alpha-helical conformation [1].	Domain
