It has been identified in nucleoside diphosphate kinases, namely Nucleoside diphosphate kinase 7 (NDK7), which contain a single copy of the DM10 domain [1,2], and in uncharacterised proteins including Rib72 from Chlamydomonas and EF-hand domain-containing protein 1/EF-hand domain-containing family member C2 (EFHC1/2) from mammals, which contain multiple copies of DM10 domains. In Chlamydomonas, and possibly mammals, DM10 domain-containing proteins are tightly bound to the flagellar doublet microtubules. This suggests that DM10 domains might act as flagellar NDK regulatory modules or as units specifically involved in axonemal targeting or assembly [3,4]. This domain have a PH-like fold which includes seven beta strands, with a short 3-4 residue helix after the first strand, and a more extended alpha helical region at the C terminus [2,3].

FtsZ is the polymer-forming protein of bacterial cell division. It is part of a ring in the middle of the dividing cell that is required for constriction of cell membrane and cell envelope to yield two daughter cells. FtsZ and tubulin are GTPases. FtsZ can polymerise into tubes, sheets, and rings in vitro and is ubiquitous in eubacteria and archaea. Tubulin is the major component of microtubules.

CFA20 is a cilium- and flagellum-specific protein that plays a role in axonemal structure organisation and motility [1,2]. In Chlamydomonas reinhardtii, it stabilises outer doublet microtubules (DMTs) of the axoneme and may work as a scaffold for intratubular proteins, such as tektin and PACRG, to produce the beak structures in DMT1 [2,3]. Other proteins contain a domain with homology to CFA20. WDR90/POC16 contains such a domain in its N terminus, followed by a large C-terminal domain with multiple WD40 repeats [2]. This domain is also present in the N terminus of uncharacterised protein C3orf67.
