This is the N-terminal domain found in components of the gamma-tubulin complex proteins (GCPs). Family members include spindle pole body (SBP) components such as Spc97 and Spc98 which function as the microtubule-organizing center in yeast [1]. Furthermore, family members such as human GCP4 (Gamma-tubulin complex component 4) have been structurally elucidated Swiss:Q9UGJ1 [2]. Functional studies have shown that the N-terminal domain defines the functional identity of GCPs, suggesting that all GCPs are incorporated into the helix of gamma-tubulin small complexes (gTURCs) via lateral interactions between their N-terminal domains. Thereby, they define the direct neighbors and position the GCPs within the helical wall of gTuRC [3]. Sequence alignment of human GCPs based on the GCP4 structure helped delineate conserved regions in the N- and C-terminal domains [2]. In addition to the conserved sequences, the N-terminal domains carry specific insertions of various sizes depending on the GCP, i.e. internal insertions or N-terminal extensions. These insertions may equally contribute to the function of individual GCPs as they have been implied in specific interactions with regulatory or structural proteins. For instance, GCP6 carries a large internal insertion phosphorylated by Plk4 and containing a domain of interaction with keratins, whereas the N-terminal extension of GCP3 interacts with the recruitment protein MOZART1[3].

This is the C-terminal domain found in components of the gamma-tubulin complex proteins (GCPs). Family members include spindle pole body (SBP) components such as Spc97 and Spc98 which function as the microtubule-organizing center in yeast [1]. Furthermore, family members such as human GCP4 (Gamma-tubulin complex component 4) have been structurally elucidated Swiss:Q9UGJ1 . Structure-based sequence analysis revealed the existence of an exposed surface area conserved in all human GCPs and in GCP4 orthologs. This area is located in the C-terminal domain of GCP4, which was confirmed in vitro to bind directly to gamma-tubulin. Sequence alignment of human GCPs based on the GCP4 structure helped delineate conserved regions in the N- and C-terminal domains [2].	Domain

This family includes the tubulin alpha, beta and gamma chains. Members of this family are involved in polymer formation. Tubulins 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. (The FtsZ GTPases have been split into their won family).	Domain
