Contributes to mitotic spindle assembly, maintenance of centrosome integrity and completion of cytokinesis as part of the HAUS augmin-like complex. Component of the HAUS augmin-like complex. The complex interacts with the gamma-tubulin ring complex and this interaction is required for spindle assembly. Interacts with EML3 (phosphorylated at 'Thr-881') (PubMed:30723163). Localizes to interphase centrosomes and to mitotic spindle microtubules. Belongs to the HAUS5 family. Extended N-terminus. Extended N-terminus.
