What's a GeneRIF?

Data suggest Greatwall kinase (Gwl) associates with protein phosphatase 1 (PP1), particularly PP1gamma subunit, which mediates dephosphorylation of Gwl Ser-883; consistent with mitotic activation of Gwl, its association with PP1 is disrupted in mitotic cells; subunits PPP1R3B and PPP1R13L associate with Gwl; thus, PPP1R3B appears to act as cell cycle regulator in oocytes that functions by governing Gwl dephosphorylation.
Title: Cell cycle-dependent regulation of Greatwall kinase by protein phosphatase 1 and regulatory subunit 3B.
Full dephosphorylation of Gwl results in complete inactivation of Arpp19 and ENSA, and dephosphorylation of mitotic substrates. this feed-back loop irreversibly induces mitotic exit.
Title: Greatwall dephosphorylation and inactivation upon mitotic exit is triggered by PP1.
study provides evidence that PP1 targets the auto-phosphorylation site of Gwl, resulting in efficient Gwl inactivation; this step is necessary to facilitate subsequent complete dephosphorylation of Gwl by PP2A-B55
Title: Protein phosphatase 1 is essential for Greatwall inactivation at mitotic exit.
we showed that the Gwl nuclear localization is indispensable for the biochemical function of Gwl in promoting mitotic entry.
Title: Regulation of Greatwall kinase by protein stabilization and nuclear localization.
PP2A-B55delta, Greatwall and ARPP19 are not only required for entry into meiotic divisions, but are also pivotal effectors within the Cdk1 auto-regulatory loop responsible for its independence with respect to the PKA-negative control.
Title: The phosphorylation of ARPP19 by Greatwall renders the auto-amplification of MPF independently of PKA in Xenopus oocytes.
Greatwall kinase and cyclin B-Cdk1 are both critical constituents of M-phase-promoting factor.
Title: Greatwall kinase and cyclin B-Cdk1 are both critical constituents of M-phase-promoting factor.
inhibition of PP2A-B55delta results from Ensa, that is phosphorylated in mitosis by the protein kinase Greatwall; this converts Ensa into specific inhibitor of PP2A-B55delta; this pathway represents a previously unknown element in mitosis control
Title: Greatwall phosphorylates an inhibitor of protein phosphatase 2A that is essential for mitosis.
3 phosphorylation sites (phosphosites) critical to Gwl activation (pT193, pT206, and pS883 in Xenopus laevis) located in evolutionarily conserved domains that differentiate Gwl from related kinases
Title: Determinants for activation of the atypical AGC kinase Greatwall during M phase entry.
Coordinated interplays between Plx1 and Gwl are required for reactivation of these kinases from the G(2)/M DNA damage checkpoint and efficient checkpoint recovery.
Title: Greatwall and Polo-like kinase 1 coordinate to promote checkpoint recovery.
mitotic entry and maintenance is not only mediated by the activation of cyclin B-Cdc2 but also by the regulation of PP2A by GW
Title: Greatwall maintains mitosis through regulation of PP2A.

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.
