Interactioni
Subunit structurei
Interacts with KATNA1. This interaction enhances the microtubule binding and severing activity of KATNA1 and also targets this activity to the centrosome (PubMed:16203747). This interaction is weakly competed by KATNBL1 which has a lower affinity for it (By similarity).
Interacts with ASPM; the katanin complex formation KATNA1:KATNB1 is required for the association of ASPM (PubMed:28436967).
Interacts with dynein, microtubules, NDEL1 and PAFAH1B1 (PubMed:16203747).
Interacts with KATNAL1; this interaction is weakly competed by KATNBL1 which has a lower affinity for it (By similarity).
Interacts with CAMSAP2 and CAMSAP3; leading to regulate the length of CAMSAP-decorated microtubule stretches (By similarity).
