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 domain is found at the C-terminal end of SAS-6 from Leishmania major (Swiss:E9AFQ5) and similar sequences found in protists. SAS-6 is a centriolar protein that oligomerises through its coiled coil (CC) domain (this entry), forming a rod-like parallel dimer [1].	Domain
