Contributes to mitotic spindle assembly, maintenance of centrosome integrity and completion of cytokinesis as part of the HAUS augmin-like complex. Promotes the nucleation of microtubules from the spindle through recruitment of NEDD1 and gamma-tubulin. Component of the HAUS augmin-like complex. The complex interacts with the gamma-tubulin ring complex and this interaction is required for spindle assembly (PubMed:19369198, PubMed:19427217). Interacts with PLK1, NEDD1 and gamma-tubulin (PubMed:19029337). Interacts with EML3 (phosphorylated at 'Thr-881') (PubMed:30723163). Localizes to interphase centrosomes and to mitotic spindle microtubules. Phosphorylated during mitosis. Belongs to the HAUS6 family. Contaminating sequence. Potential poly-A sequence. Truncated N-terminus. Truncated N-terminus. Truncated N-terminus. Truncated N-terminus. Truncated N-terminus.
