Comments
Mad1 is a spindle assembly checkpoint (SAC) protein. It resides at nuclear pore complex in interphase and are recruited to kinetochores before spindle attachment. SAC-induced accumulation of Mad1 to kinetochores is dependent on CRM1, RanGTP, and NES.

User Input
Accurate identification of NESs is difficult because many sequences in the genome match the NES consensus. Therefore, some published NESs may be mistakenly identified. Please help us improve the accuracy of NESdb by providing either a positive or negative flag for the NES in this entry. Supporting comments are required to process the flag.
