A, B	PF22331	Sas-6-like, oligomerization domain (Sas-6-like_oligomerization)	Sas-6-like, oligomerization domain	This entry represents the coiled-coil region of Sas-6 from Chlamydomonas reinhardtii, which mediates oligomerization [1,2]. In human, Sas-6 is essential for the onset of procentriole formation and accumulates on the torus where Plk4 has focused.	Domain
A, B	PF16531	Centriolar protein SAS N-terminal domain (SAS-6_N)	Centriolar protein SAS N-terminal domain	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. ...	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
