Summary: Predicted to enable protein phosphatase 2A binding activity and protein serine/threonine kinase activity. Acts upstream of or within female meiosis II and positive regulation of ubiquitin protein ligase activity. Predicted to be located in centrosome; cleavage furrow; and nucleoplasm. Predicted to be active in nucleus. Is expressed in several structures, including early conceptus; otic capsule; secondary oocyte; thymus primordium; and tooth. Human ortholog(s) of this gene implicated in thrombocytopenia. Orthologous to human MASTL (microtubule associated serine/threonine kinase like). [provided by Alliance of Genome Resources, Apr 2025]

reveal an unexpected role of Mastl in actin cytoskeletal dynamics in postmitotic cells and suggest that the thrombocytopenia-associated mutation in MASTL is a pathogenic dominant mutation that mimics decreased PP2A activity resulting in altered phosphorylation of cytoskeletal regulatory pathways.
Title: Thrombocytopenia-associated mutations in Ser/Thr kinase MASTL deregulate actin cytoskeletal dynamics in platelets.
Findings reveal the role of RSK in mouse oocytes, showing that the RSK-MASTL pathway allows mammalian-specific prolonged meiotic exit and ensures the faithful conversion from sperm to paternal pronuclei.
Title: RSK-MASTL Pathway Delays Meiotic Exit in Mouse Zygotes to Ensure Paternal Chromosome Stability.
using in vitro dephosphorylation assays, we demonstrate that Mastl promotes persistent MPS1 phosphorylation by inhibiting PP2A/B55-mediated MPS1 dephosphorylation rather than affecting Cdk1 kinase activity. Our findings establish a key regulatory function of the Greatwall kinase/Mastl - PP2A/B55 pathway in preventing premature SAC silencing
Title: Loss of the Greatwall Kinase Weakens the Spindle Assembly Checkpoint.
Mastl is required for the timely activation of anaphase-promoting complex/cyclosome to allow meiosis I exit and for the rapid rise of Cdk1 activity.
Title: Mastl is required for timely activation of APC/C in meiosis I and Cdk1 reactivation in meiosis II.
Data show that Mastl (Greatwall)-null cells display mitotic collapse after nuclear envelope breakdown (NEB) characterized by defective chromosome condensation and prometaphase arrest.
Title: Greatwall is essential to prevent mitotic collapse after nuclear envelope breakdown in mammals.

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.
