  "account": "ANKLE2 is a scaffolding protein essential for neuroprogenitor cell division and embryonic brain development. Mutations in the ANKLE2 gene lead to primary microcephaly, a congenital disorder marked by disrupted neurodevelopment. However, the specific mechanism by which ANKLE2 mutations cause microcephaly remains unclear. This study elucidates the interaction network of ANKLE2, encompassing proteins involved in cell division and novel candidates associated with microcephaly within the APC (anaphase-promoting complex). Analysis of six pathogenic variants uncovers alterations in this interaction network that likely contribute to microcephaly. Employing molecular simulations, the researchers identify structural ramifications of five pathogenic substitutions, including disruptions to crucial helical structures. Collectively, these findings suggest that the loss of interaction with the PP2A (protein phosphatase 2A) complex serves as a common pathogenesis mechanism for ANKLE2 mutations. Phosphoproteomics uncovers extensive changes in ANKLE2- and PP2A-dependent phosphorylation patterns across various cell division proteins. By integrating proteomics and simulation methods, this research enhances our molecular comprehension of ANKLE2 function and the pathogenic alterations associated with primary microcephaly.",
  "summary": "ANKLE2 is a scaffolding protein with crucial roles in neuroprogenitor cell division and embryonic brain development. Pathogenic variants in ANKLE2 cause primary microcephaly, a congenital disorder characterized by impaired neurodevelopment. Nonetheless, the underlying dysfunction of ANKLE2 is not understood. Here, we define the ANKLE2 protein interaction landscape, which includes cell division…",
