蛋白质信息 (UniProt)

着丝粒蛋白W (CENP-W) (癌上调基因2蛋白)

Q5EE01

功能描述

CENPA-NAC(核小体相关)复合物的组分,该复合物在kinetochore蛋白组装、有丝分裂进程和染色体分离中起核心作用 (By similarity)。CENPA-NAC复合物招募CENPA-CAD(核小体远端)复合物,可能参与新合成的CENPA整合到着丝粒中 (By similarity)。核小体相关复合物的一部分,该复合物特异性结合着丝粒处含有histone H3的核小体,而非含有CENPA的核小体。异四聚体CENP-T-W-S-X复合物的组分,该复合物结合并超螺旋化DNA,在kinetochore组装中起重要作用。CENPW在kinetochore组装和功能中起基础性作用。它是内kinetochore蛋白之一,大多数其他蛋白在其下游结合。正常的染色体组织和正常的有丝分裂进程所必需。 {ECO:0000250, ECO:0000269|PubMed:19070575, ECO:0000269|PubMed:19533040, ECO:0000269|PubMed:21695110, ECO:0000269|PubMed:22002061, ECO:0000269|PubMed:22304917}。

组织特异性

Highly expressed in ovary, liver, lung and pancreas and to a lower extent in breast and gastrointestinal tract cancers; such as those of the colon, rectum and stomach. Overexpressed in high grade breast invasive tumors. Expressed in many cancer cell types.
