Target

Full Name
NDC80 kinetochore complex component
Introduction
This gene encodes a component of the NDC80 kinetochore complex. The encoded protein consists of an N-terminal microtubule binding domain and a C-terminal coiled-coiled domain that interacts with other components of the complex. This protein functions to organize and stabilize microtubule-kinetochore interactions and is required for proper chromosome segregation. [provided by RefSeq, Oct 2011]

Alternative Names
NDC80, Kinetochore Complex Component; Retinoblastoma-Associated Protein HEC; Highly Expressed In Cancer Protein; Kinetochore-Associated Protein 2; Kinetochore Associated 2; Kinetochore Protein Hec1; HsHec1; KNTC2; HEC1; HEC;
Function
Acts as a component of the essential kinetochore-associated NDC80 complex, which is required for chromosome segregation and spindle checkpoint activity (PubMed:9315664, PubMed:12351790, PubMed:14654001, PubMed:14699129, PubMed:15062103, PubMed:15235793, PubMed:15239953, PubMed:15548592, PubMed:16732327, PubMed:30409912).

Required for kinetochore integrity and the organization of stable microtubule binding sites in the outer plate of the kinetochore (PubMed:15548592, PubMed:30409912).

The NDC80 complex synergistically enhances the affinity of the SKA1 complex for microtubules and may allow the NDC80 complex to track depolymerizing microtubules (PubMed:23085020).

Plays a role in chromosome congression and is essential for the end-on attachment of the kinetochores to spindle microtubules (PubMed:25743205, PubMed:23891108).

Cellular Location

Other locations
kinetochore
Note: Localizes to kinetochores from late prophase to anaphase (PubMed:14699129). Localizes specifically to the outer plate of the kinetochore (PubMed:14699129).
PTM
Phosphorylation begins in S phase of the cell cycle and peaks in mitosis. Phosphorylated by NEK2. Also phosphorylated by AURKA and AURKB.
Acetylated at Lys-53 and Lys-59 by KAT5 during mitosis, promoting robust kinetochore-microtubule attachment (PubMed:30409912). Deacetylated by SIRT1 (PubMed:30409912).
