Kinetochore protein NDC80 homolog is a protein that in humans is encoded by the NDC80 gene.^[1][2][3]

HEC is one of several proteins involved in spindle checkpoint signaling. This surveillance mechanism assures correct segregation of chromosomes during cell division by detecting unaligned chromosomes and causing prometaphase arrest until the proper bipolar attachment of chromosomes is achieved.[supplied by OMIM]^[3]

Interactions

NDC80 has been shown to interact with MIS12,^[4][5] NEK2^[6][7] and PSMC2.^[7]
