What's a GeneRIF?

CENP-Q - a subunit of the CENP-O complex (comprising CENP-O, CENP-P, CENP-Q and CENP-U) that targets polo-like kinase (Plk1) to kinetochores - is also required for the recruitment of CENP-E to kinetochores.
Title: Chromosome congression is promoted by CENP-Q- and CENP-E-dependent pathways.
Plk1 regulates the timing of the delocalization and ultimate destruction of the PBIP1.CENP-Q complex.
Title: Mammalian Polo-like kinase 1 (Plk1) promotes proper chromosome segregation by phosphorylating and delocalizing the PBIP1·CENP-Q complex from kinetochores.
Data propose that CENP-P/O/R/Q/U self-assembles on kinetochores with varying stoichiometry and undergoes a pre-mitotic maturation step that could be important for kinetochores switching into the correct conformation for microtubule-attachment.
Title: Step-wise assembly, maturation and dynamic behavior of the human CENP-P/O/R/Q/U kinetochore sub-complex.
Mammalian polo-like kinase 1-dependent regulation of the PBIP1-CENP-Q complex at kinetochores.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
